The use of a multidisciplinary panel with experience in epidemiology and EBM limits the effect of using a non-representative sample, and the use of the Delphi tool is well recognised for developing consensus in healthcare science.38 The selection of a Delphi group is very important as it effects the results of the process.31 As CSSs are used extensively in human and veterinary research, it was appropriate to use expertise from both of these fields. Were the groups comparable? During round 1 (undertaken in February 2013) of the Delphi process, 20 components reached consensus, 13 components were assessed to require modification and it was deemed appropriate to remove 4 components from the tool. - Key areas addressed in the AXIS include - Study Design, Sample Size Justification, Target Population, Sampling Frame, Sample Selection, Measurement Validity & Reliability, and Overall Methods. 0000116000 00000 n The null hypothesis is that there is no difference in the prevalence of MMC between (i) countries, (ii) gender, (iii) age groups, and (iv) left-right MM1s.
