^aControlled for sex, extroverted personality, suspicious personality, currently on medication, education, any comorbidity, any symptoms in the past 30 days, rural residence, family disease history, and antipsychotic dosage at discharge using propensity scores

^bOnly one cutoff (age 14.7) is used for the onset of psychotic symptom models because the models using age 13.0 did not converge
