Figure 2

Illustration of domain-theme mapping tallies by simple- and frequency-weighting. (a) All included outcome measures are listed alongside the number of studies which utilise them and the domains which are covered within each measure. (b) All included domains are mapped to themes. (c) Simple count collates the number of domains within each theme; frequency-weighted count multiplies each included domain within a theme by the number of studies using the outcome measure from which it originated (in this example, anxiety and depression (underlined) are both counted as 3 due to the outcome measure they originate from (caregiver anxiety and depression) being used in 3 of the included studies. Totals are represented in spider plots of both the simple count (d) and frequency-weighted (e) tallies.
