Results Summary and Professional Abstract
|Article Highlight: This project reported in BMC Musculoskeletal Disorders that more physical therapy visits was associated with more improvement in various areas such as pain levels and knee function, for people with knee osteoarthritis. The study, which included 259 participants, also found more-frequent use of online exercise training was not associated with greater improvement in the same areas.|
|This project's final research report is expected to be available by June 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. Those comments and responses included the following:
- The reviewers noted that the draft report emphasized within-group improvements on outcomes, showing that patients in both treatment groups improved, rather than the differences between the two treatments and the wait-list control. The researchers acknowledged this and revised the report to emphasize the between-group differences instead, since this was the focus of the study.
- The reviewers asked the researchers to clarify whether the study had sufficient power to detect a true clinically significant difference given that the patient attrition rate was higher than expected. The researchers added a study limitation related to the attrition rate.
