Abbreviations: ER, emergency room; MPR, medication possession ratio; PANSS, positive and negative syndrome scale; SD, standard deviation; SF-36, Medical Outcome--Short Form 36. Possible PANSS scores range from 30 to 210, with higher scores indicating greater pathology. SF-36 standardized scores are relative to the general population, where smaller negative scores indicate better health.

^aAdjusted p value for age, gender, and ethnicity.
