Due to missing data, n = 358–370 across characteristics for the total analytic sample. For experimental condition analytic subsamples: n = 58–61 for Black MSM, n = 64–65 for White MSM, n = 63 for Black MSW (no missing data), n = 54–56 for White MSW, n = 59–64 for Black MID, and n = 59–61 for White MID
