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:
- The reviewers noted that the report emphasized the secondary outcomes results over the primary outcome, blood pressure control. They asked the researchers to revise the report to make sure that the primary outcome results were more prominent even though the results did not show a difference between the two interventions. The researchers acknowledged that there were no between-group differences in blood pressure control based on treatment arm but pointed out that a major goal of the study was to see if the interventions could attenuate the health disparities for known at-risk groups. For this reason, they felt it was particularly important to show the effects of the collaborative care intervention on particular subgroups of patients.
- The reviewers were unclear on whether the researchers assessed blood pressure control disparities between Black and White patients in the participating clinics at baseline, given the focus on disparities in treatment outcomes. The researchers explained that they could not assess the level of disparity in blood pressure control at baseline overall because they only collected data on study participants, who all had uncontrolled blood pressure. However, the researchers did identify differences in systolic and diastolic blood pressure at baseline by racial and ethnic group and reported those differences in the text. They also noted some treatment differences at 12 months by racial and ethnic group.
- The reviewers asked for more information about plans to analyze the results after imputing missing data. The researchers added information about the imputation analyses they had completed to account for missing data under the assumption that the data were missing at random. The researchers explained that they would complete additional analyses later after investigating potential reasons for some of the missing data.
