  1. DUP duration of untreated psychosis, PSA physical/sexual abuse.
  2. aNumber of male early psychosis patients (EPP) included in the clinical study.
  3. bNumbers of male EPP in the 1st (<6 months after reaching psychosis threshold) and 2nd (6–12 months after reaching psychosis threshold) clinical assessment time-points. Data specific to each of the two evaluation periods are displayed when relevant.
  4. cTest values provided by one way ANOVA (F) or Likelihood ratio (λ) to test for difference between trauma (physical/sexual abuse) groups, at each time point (>6 months and between 6-12 months after psychosis threshold) when relevant.
