adj.-R2: adjusted coefficient of determination, ß0: intercept, b: regression coefficient, ß: standardized regression coefficient. Only variables with significant regression coefficients were retained by the respective model through step-wise forward selection (inclusion cut-off p < 0.05; exclusion cut-off p ≥ 0.10) unless otherwise indicated. Ø denotes p > 0.05, * denotes p < 0.05, ** denotes p < 0.01, *** denotes p < 0.001. Information on log-linear models M1.S, M2.S and M3.S are provided in the Supplementary Material, section ‘Model equations’
