Summary of Findings From a letter to the editor raising concerns about one systematic review of effectiveness of manual therapy on pain, physical function, and nerve conduction studies in carpal tunnel syndrome patients published in 2022.The letter authors highlight that the systematic review included 4 papers which appear to have come from the same 2 studies. In the first case this was based on the overlapping time period, same committee with the same decision number, and the same inclusion and exclusion criteria. In the second case one paper was a secondary analysis which shared the same clinical trials numbers with another; they had the same exclusion criteria and inclusion criteria, and study time period was the same. The authors highlight the possibility that data could have been included twice in the meta-analysis.
