a
Persistence is defined as the number of individuals with an STB both within and prior to the past 12 months divided by the total number of individuals with that STB; Age of Onset and Persistence items were missing from the following: Age of Onset (Ideation = 7, Plan = 2, Attempt = 3) and Persistence (Ideation = 7, Plan = 12, Attempt = 12); CI = Confidence Interval.
