  1. This analysis uses the time frame between the screening and baseline clinic visits as the reference period for determining “treatment-emergent.” For each category, the population (= m) only includes treated participants for whom worsening from the reference period was possible. For suicidal ideation categories, worsening is defined as an increasing progression from one category to another along the spectrum (from passive down to active—method, intent, and plan). For suicidal behavior categories, worsening is defined as an increasing progression from one category to another along the spectrum (from preparatory actions or behaviors down to completed suicide)
