Conclusions: As with other evidence-based initiatives, the AXIS tool is intended to be an organic item that can change and be improved where required, with the validity of the tool to be measured and continuously assessed. A recent study has found that the tool takes longer to complete than other tools (the investigators took a mean of 8.8 minutes per person for a single predetermined outcome using our tool compared with 1.5 minutes for a previous rating scale for quality of reporting).22 The reliability of the tool has not been extensively studied, although the same authors observed that larger effect sizes . Training & Events. If participants failed to respond to a specific round, they were still included in the following rounds of the Delphi process. It is therefore the responsibility of the appraiser of the study to recognise omissions in reporting and consider how this affects the reliability of the results.
