Abbreviations: OR, odds ratio; PE, psychotic experience; STB, suicidal thoughts and behaviors.

a

Psychotic experience (any PE, number of PE type, and frequency metric) was used as a predictor of STB outcomes in separate discrete-time survival models. These models control for age cohorts, sex, person-year dummies, and country.

b

These models additionally control for 21 other antecedent mental disorders.

c

Statistically significant at the P <.05 level (Wald χ2 based on discrete-time survival models) using 2-sided tests.
