Peer review of PCORI-funded research helps make sure the report presents complete, balanced, and useful information about the research. It also assesses how the project addressed PCORI’s Methodology Standards. During peer review, experts read a draft report of the research and provide comments about the report. These experts may include a scientist focused on the research topic, a specialist in research methods, a patient or caregiver, and a healthcare professional. These reviewers cannot have conflicts of interest with the study.
The peer reviewers point out where the draft report may need revision. For example, they may suggest ways to improve descriptions of the conduct of the study or to clarify the connection between results and conclusions. Sometimes, awardees revise their draft reports twice or more to address all of the reviewers’ comments.
Peer reviewers commented, and the researchers made changes or provided responses. Those comments and responses included the following:
- Overall, reviewers’ comments were positive about the quality of this final report.
- Reviewers asked for additional information on subgroup analyses, particularly related to race and ethnicity. The researchers acknowledged limitations in being able to conduct these analyses because of the underrepresentation of minority status groups other than for African Americans in the geographic area of the study. The report does present the researchers’ analyses of outcome differences between African-American and white study participants.
- Reviewers asked the researchers to speculate on why attrition was higher than expected in this study. The researchers noted that higher attrition happened after enrollment but before the baseline assessment, while attrition postbaseline was as expected.
