The initial review of existing tools and texts identified 34 components that were deemed relevant for CA of CSSs and were included in the first draft of the tool (see online supplementary table S2). Fundamentally, the tool developed by Berra et al15 only appraises the quality of reporting of CSSs and does not address risk of bias or other aspects of study quality.16 Good quality of reporting of a study means that all aspects of the methods and the results are presented well and in line with international standards such as STROBE;17 however, this is only one aspect of appraisal as a well-reported study does not necessarily mean that the study is of high quality.
