Cumulative probability of suicidal thoughts or behaviors in a target population of US adults living with human immunodeficiency virus who initiated first-line antiretroviral therapy between 1999 and 2015. The probability of suicidal thoughts/behaviors was estimated as 1 minus the inverse odds–weighted Kaplan-Meier estimate. The y-axis is truncated at 5%. Thirty imputed data sets were constructed, and the resulting 30 weighted Kaplan-Meier estimates were averaged at each time point. Crude number of events and number of participants at risk (n)—for the “with EFV” group (39 suicidal thoughts/behavior events): week 0, n = 2,323; week 48, n = 1,786; week 96, n = 1,238; week 144, n = 530; week 192, n = 59; for the “without EFV” group (13 events): week 0, n = 1,626; week 48, n = 1,326; week 96, n = 1,019; week 144, n = 491; week 192, n = 71.
