Models also included Time as a covariate. For ‘All predictors + significant time interactions’, Type III tests for the predictor*time interactions are shown only. There were no material changes in significance of main effects. QIC is a relative, ‘lower is better’ measure of goodness of fit. Bold indicates statistical significance. W χ²: Wald Chi-square, Β: Beta parameter, SE: Standard Error, CI: Confidence Interval.
