This has implications for interpretation after using the tool as there will be differences in individuals judgements. 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. The interests and experiences of the panel will clearly have had an effect on the results of this study as this is common to all Delphi studies.31 ,41 The majority of Delphi studies are conducted using between 15 and 20 participants,31 so a panel of 18 is consistent with other published Delphi panels.
