Legend: Results derived from multivariate analyses and uni/bivariate analyses (in parenthesis) are presented. K, number of samples. Positive (++) was used for percentage K ≥75% and (+) for percentage K between 50-75% for both bivariate and multivariate associations; 0/+ or 0/- when the evidence was split between no association (0) and either positive or negative associations, respectively; (?) for other results indicating inconsistent findings or indeterminate results (i.e., when only a small number of studies were available, marked with *).
