Research question one – chart of reviews by number of studies reviewed and total participants. Note: Given all reviews for research question one were plotted (k = 39), the X-axis was removed as it represents sequential numbering only. The Y axis represents the number of studies in each review and bubble size indicates the total number of participants (where available). Total n was not calculated as studies may be in multiple reviews [23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60]
