  1. Coding: n/N number of significantly associated relationships divided by total number of relationships. # number of relationships reported with study reference number in brackets. Statistical association: + positive statistical correlations, negative statistical correlations, +/− includes both positive and negative statistical correlations. Practical interpretation: clear association (≥ 60% of total relationships are significantly associated), uncertain association (34–59% of total relationships are significantly associated), no association (≤ 33% of total relationships are significantly associated), unknown conclusion (< 5 total relationships reported)
