Results of longitudinal logistic models on categorical clinical outcomes and of Cox-proportional hazards model on time to early discharge. Pairwise differences between course of cannabis use classes are shown at baseline, 12-month follow-up, and the change between baseline and 12 months. Overall joint tests were also computed for each set of pairwise comparisons.
