Traditionally, evidence-based practice has been about using systematic reviews of randomised controlled trials (RCTs) to inform the use of interventions.10 However, other types/designs of research studies are becoming increasingly important in evidence-based practice, such as diagnostic testing, risk factors for disease and prevalence studies,10 hence systematic reviews in this area have become necessary. This view is also seen in other appraisal tools, is shared by other researchers and can be seen by the absence of questions relating to the discussion sections in CA tools for other types of studies.12 ,16 ,20 ,28 ,36. 0000005423 00000 n OARSI recommendations for the management of hip and knee osteoarthritis, part I: critical appraisal of existing treatment guidelines and systematic review of current research evidence.

A relatively high prevalence of CKD, especially in older patients and those with diabetic complications-related to poor glycaemic control, was encountered in this primary care practice, which may help to target optimise care and prevention programs for CKD among T2DM patients. 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.
