PE, Psychotic experiences; OR, Odds ratio; CI, Confidence interval

Significant at the .05 level, 2-sided test

Any PE was used as a predictor of STB outcomes in a discrete-time survival model controlling for age-cohorts, gender, person-year dummies and country.

These models additionally control for 21 other temporally-ordered mental disorders.
