GAF = Global Assessment of Functioning; SAPS = Scale for the Assessment of Positive Symptoms; AD = antidepressants; HAM-D = Hamilton Depression Rating Scale; BPRS = Brief Psychiatric Rating Scale; AP = antipsychotics; MS = mood stabilizers.

^aAll analyses controlled for the length of follow-up. Intercepts were computed so that they corresponded to the best scores on all relevant predictors, except for age and GAF (centered at sample averages: 30 years and GAF of 70).

^bB reflects the difference between the highest and lowest scores observed, except for age and GAF as sample averages were used for those variable instead of lowest scores.
