Summary of Findings	From a letter reporting concerns about the methodology of a systematic review of a bladder cancer monitor for detecting non-muscle invasive bladder cancer recurrences published in 2021. The letter highlights that the review authors included several studies that appeared to share overlapping data. Reportedly the review authors did not provide analytical evidence to support the attributed factors that might have caused the observed heterogeneity in reported diagnostic accuracy among studies.
Did the article find that the problem(s) led to qualitative changes in interpretation of the results?	Not Applicable
Are the methods of the article described in enough detail to replicate the study?
