  1. aThe number of significant results (when present) is reported in brackets for each variable. Please note that such numbers refer to the papers, and that more than one variable in the same row could be analysed in the same paper; moreover, not all studies conduct both bivariate and multivariate analysis
  2. “Mixed direction” means that the variable resulted significant in more than one paper, but the results were contrasting
  3. bplus two cases of not monotonic direction; cplus one case with contrary result
