string(1647) "Background:
The lack of population representativeness in clinical trial study samples has been a persistent problem that has been observed across disease domains. Numerous studies have shown the differences between real-world patients and clinical trial study samples. This problem is significant in that the lack of population representativeness can compromise the generalizability of clinical trial results and lead to unforeseen adverse events among the real-world patients. It is imperative to improve the transparency of the population representativeness of clinical trial samples using systematic analyses.
Objective:
Our study aims to develop a quantitative metric that is able to quantify the population representativeness of each trial using multiple study traits while accounting for their dependencies and relevancies.
Study Design:
We will design and validate the population representative metric by comparing patient-level clinical trial sample to real-world target populations made available by electronic health records. For each trial, we will identify the real-world target population in our institution?s clinical data warehouse, which contains 4.5 million patients? 20 years of data. We will profile the study samples and the target population for each trial and measure the representativeness of study sample of the target population.
Participants:
all enrolled patients in the trials.
Main outcome measures:
a score of population representativeness of each trial
Statistical analysis:
our metric for representativeness is statistically-based"
["project_brief_bg"]=>
string(1888) "In every study, investigators need to extrapolate study results from the Study Sample, which comprises all the individuals enrolled in a study, to the Target Population, which comprises all individuals for whom a treatment may be considered for its intended purpose. The Sample population is recruited from and is a subset of a Study Population, which is defined by the eligibility criteria and comprises all individuals who would be eligible to enroll in that study. Thus the population representativeness of the Study Population is a function of the eligibility criteria and directly influences the generalizability of the study results. Ideally, the definition of the study population should be optimized to reflect the target population. Since it is impossible to accurately profile the Target Population A, we can approximate A by profiling all the members of A who have EHR data, which we call Target Population with EHRs.
Our core hypothesis is that the more accurately clinical investigators can characterize the target population as defined by EHR data -- the better informed and prepared they will be able to define eligibility criteria to construct the study population to appropriately represent the true Target Population. This research will help cultivate a new culture of clarity and transparency about eligibility criteria, in which investigators are expected and supported to explain and justify the rationale for their eligibility criteria choices. Such transparency will enable more effective measures to reduce clinical research biases and improve research reliability.
This research promises to improve the transparency of the population representativeness of clinical research eligibility criteria and hence reduce biases and improve research reliability, and enable early iterative in silico estimates of feasibility and population representativeness"

1. all study samples in the Yoda database: we will include both clinical and demographic characteristics for profiling the study samples in clinical trials. For example, in our 2014 paper, we compared the distributions of A1c and age between the real-world diabetes patients and the study populations (derived from eligibility criteria) of 1761 Type 2 diabetes trials. We will look at the inclusiveness of individual traits as well as the combination of all the traits used in clinical trials. We prefer to use individual-level data instead of summary statistics because our methodology for quantifying population representativeness involves the identification of the fraction of the diseased population who are part of the trial. Using individual-level data will provide more precise results than summary statistics and allows to uncover overly restrictive eligibility criteria and provide this feedback to trial designers. Morever, existing summary statistics inlcudes only mean, max, or min values; however, we need to use other measures that are more appopriate than mean etc.

We are measuring the "likelihood" of a clinical trial's findings being applied to patients who were not a part of the trial based on (a) eligibility criteria (b) actual trial patients. We will use all features (both quantitative and categorical) that are a part of the eligibility criteria of the study. The individual patient data will be used to evaluate what fraction of the diseased population is represented in the trials.
We will be happy to provide a copy of our manuscript with details for our quantitative metric for population representativeness upon publication. We have used other public data sources to develop this metric and will be interested in applying this metric on the Yoda database."

Project Title:
Population Representativeness of Clinical Trial Study Samples
Scientific Abstract:
Background:
The lack of population representativeness in clinical trial study samples has been a persistent problem that has been observed across disease domains. Numerous studies have shown the differences between real-world patients and clinical trial study samples. This problem is significant in that the lack of population representativeness can compromise the generalizability of clinical trial results and lead to unforeseen adverse events among the real-world patients. It is imperative to improve the transparency of the population representativeness of clinical trial samples using systematic analyses.
Objective:
Our study aims to develop a quantitative metric that is able to quantify the population representativeness of each trial using multiple study traits while accounting for their dependencies and relevancies.
Study Design:
We will design and validate the population representative metric by comparing patient-level clinical trial sample to real-world target populations made available by electronic health records. For each trial, we will identify the real-world target population in our institution?s clinical data warehouse, which contains 4.5 million patients? 20 years of data. We will profile the study samples and the target population for each trial and measure the representativeness of study sample of the target population.
Participants:
all enrolled patients in the trials.
Main outcome measures:
a score of population representativeness of each trial
Statistical analysis:
our metric for representativeness is statistically-based
Brief Project Background and Statement of Project Significance:
In every study, investigators need to extrapolate study results from the Study Sample, which comprises all the individuals enrolled in a study, to the Target Population, which comprises all individuals for whom a treatment may be considered for its intended purpose. The Sample population is recruited from and is a subset of a Study Population, which is defined by the eligibility criteria and comprises all individuals who would be eligible to enroll in that study. Thus the population representativeness of the Study Population is a function of the eligibility criteria and directly influences the generalizability of the study results. Ideally, the definition of the study population should be optimized to reflect the target population. Since it is impossible to accurately profile the Target Population A, we can approximate A by profiling all the members of A who have EHR data, which we call Target Population with EHRs.
Our core hypothesis is that the more accurately clinical investigators can characterize the target population as defined by EHR data -- the better informed and prepared they will be able to define eligibility criteria to construct the study population to appropriately represent the true Target Population. This research will help cultivate a new culture of clarity and transparency about eligibility criteria, in which investigators are expected and supported to explain and justify the rationale for their eligibility criteria choices. Such transparency will enable more effective measures to reduce clinical research biases and improve research reliability.
This research promises to improve the transparency of the population representativeness of clinical research eligibility criteria and hence reduce biases and improve research reliability, and enable early iterative in silico estimates of feasibility and population representativeness
Specific Aims of the Project:
The specific aims of this project are
(a) developing a multi-feature representativenss metric
(b) measuring the population representativness of the study samples of the included 123 trials in the Yoda database

Software Used:
Data Source and Inclusion/Exclusion Criteria to be used to define the patient sample for your study:
Data sources:
1. all study samples in the Yoda database: we will include both clinical and demographic characteristics for profiling the study samples in clinical trials. For example, in our 2014 paper, we compared the distributions of A1c and age between the real-world diabetes patients and the study populations (derived from eligibility criteria) of 1761 Type 2 diabetes trials. We will look at the inclusiveness of individual traits as well as the combination of all the traits used in clinical trials. We prefer to use individual-level data instead of summary statistics because our methodology for quantifying population representativeness involves the identification of the fraction of the diseased population who are part of the trial. Using individual-level data will provide more precise results than summary statistics and allows to uncover overly restrictive eligibility criteria and provide this feedback to trial designers. Morever, existing summary statistics inlcudes only mean, max, or min values; however, we need to use other measures that are more appopriate than mean etc.
2. EHR-based target population characteristics from our institutional clinical data warehouse
Primary and Secondary Outcome Measure(s) and how they will be categorized/defined for your study:
1. population representativeness of each clinical trial based on the combination of multiple eligibility criteria/study traits
2. population representativeness of each eligibiltiy criterion/each trait
Main Predictor/Independent Variable and how it will be categorized/defined for your study:
None
Other Variables of Interest that will be used in your analysis and how they will be categorized/defined for your study:
None
Statistical Analysis Plan:
We will use a quantitative metric to analyze population representativeness. All traits will be weighted by using EHR data to model the dependencies between multiple traits (also accounting for feature weights). The metric has several of the expected mathematical properties which will be verified through simulation-based evaluations. We are measuring the "likelihood" of a clinical trial's findings being applied to patients who were not a part of the trial based on (a) eligibility criteria (b) actual trial patients. We will use all features (both quantitative and categorical) that are a part of the eligibility criteria of the study. The individual patient data will be used to evaluate what fraction of the diseased population is represented in the trials.
We will be happy to provide a copy of our manuscript with details for our quantitative metric for population representativeness upon publication. We have used other public data sources to develop this metric and will be interested in applying this metric on the Yoda database.
Narrative Summary:
Population representativeness of clinical trial study samples directly influences the generalizability of clinical trial results. We aim to develop a multivariate representativeness measure to quantify the population representativeness of the study samples of each clinical trial. We will compare the clinical trial study samples to real-world patients using this measure.
Project Timeline:
we expect to use 1 year to complete this project:
months 1-3: data collection
months 4-6: study sample and target population profiling
months 4-9: population represetnativess analysis and evaluation
months 6-12: publication
Dissemination Plan:
we will publish and present our methods and findings in peer-reviewed mainstream informatics journals and conferences.
