What does it mean? This is particularly so where the areas of study do not lend themselves to research designs appropriate to intervention studies (i.e. The AXIS tool focuses mainly on the presented methods and results. 0000118764 00000 n Two systematic reviews failed to identify a standalone appraisal tool specifically aimed at CSSs.12 ,13 Katrak et al identified that CA tools had been formulated specifically for individual research questions but were not transferable to other CSSs. With the reduction in the number of questions and modification of the wording, comments in round 2 reflected the positive nature to the usability of the tool.I like the fact that it is quite simplenot too overloaded with methodological questions.

In some cases, longitudinal studies can last several decades. Prior to conducting the Delphi process, it was agreed that consensus for inclusion of each component in the tool would be set at 80%.31 ,32 This meant that the Delphi process would continue until at least 80% of the panel agreed a component should be included in the final tool. 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.
