  1. *n = number of studies reporting domains. 7/9 studies reported statistical significance (incl. legend) and/or p-values; **Information is based on main models and pooled data when available (if not, data of separate models/classes was used). Some studies included more than one attribute related to a particular domain. Totals could hence exceed the total number of studies incorporated.
