Adherence
Defining 'non-responders' is methodologically challenging and depends heavily on the threshold used (e.g., measurement error vs. clinical significance), leading to inconsistent classification across studies.
Be cautious when comparing 'success rates' of exercise programs. One study's 'non-responder' might be another's 'responder' due to different measurement standards. Focus on your own progress rather than population statistics.
GoodQualifiesMEDIUM confidence
Apart from this limitation, multiple definitions were used to distinguish CRF response from non-response... Few studies have used technical error (TE)... to define CRF response.
Why this rating
Based on review of multiple RCTs and their analytical limitations.
