indicates significance at alpha=0.05. Odds of transitioning to more or less severe classes are based on a reference group of staying in the same class and are only reported for baseline characteristics that were significant in the omnibus multinomial logistic regression. Abbreviations: OR=Odds ratio, 95% CI= 95% confidence interval.
