Linear regression table performed ln(PAPi) as the dependent variable. Beta coefficient for each predictor was exponentiated to geometric mean difference (odds ratio) per unit change in predictor. Geometric mean adjusted to reflect percent change in PAPi per unit change in covariate. Adjusted values are based on Bonferroni–Holm correction.
