|This project's final research report is expected to be available by September 2019.|
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. The comments and responses included the following:
- Reviewers noted that the report referred to subgroup analyses based on cancer types that could not be conducted, due to limited recruitment of patients with certain cancer types. Reviewers asked the researchers to provide additional information about the different cancer types they had planned on including and why. The researchers responded by removing all reference to subgroup analyses by cancer type, saying that these analyses were not in the original study aims.
- The reviewers said data collection time points were not clear and the analyses did not account for varying time points in intervention exposure. The researchers said they delivered interventions in face-to-face meetings during regularly scheduled visits to the cancer center. They stated that they did not collect data about the timing of these visits. They added a limitation to their discussion regarding the inability to adjust for differences in intervention exposure time points.
