  1. *n = number of studies reporting domains. All nine studies reported statistical significance; ** Information is based on main models and pooled data when available (if not, data of separate models/classes wasused). Some studies included more than one attribute related to a particular domain. Totals could hence exceed the total number of studies incorporated.
