Significant at the .05 level, 2-sided test

PE (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, gender, person-year dummies and country.

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