t-test for general(ized) linear mixed model factor or numeric (equivalent for control models) time coefficient **p < 0.01, *p < 0.05, †p < 0.1. Numeric-time model results shown in series header; factor-time model results displayed inline.

a Numeric time variable general linear mixed model residuals non-normal; Gamma mixed model with log link reported.

b Factor time variable general linear mixed model residuals non-normal; Gamma mixed model with log link reported.
