As an interim measure to a review of the handbooks, this paper presents a forward-thinking However, the purpose of a Delphi study is to purposely hand pick participants that have prior expertise in the area of interest.40 The Delphi members came from a multidisciplinary network of professionals from medicine, nursing and veterinary medicine with experience in epidemiology and EBM/EVM and exposure to teaching and areas of EBM that were not just focused on systematic reviews of RCTs. A correlates review (see section 3.3.4) attempts to establish the factors that are associated or correlated with positive or negative health behaviours or outcomes.Evidence for correlate reviews will come both from specifically designed correlation studies and other study designs that also . 2023 The AXIS tool is therefore unique and was developed in a way that it can be used across disciplines to aid the inclusion of CSSs in systematic reviews, guidelines and clinical decision-making.
