aThe square root transformation was used to help normalize the distribution of unprotected acts, and 5 linear regression models were fit to the transformed outcome. Model 1 included the unwanted sexual activity during childhood indicator only. Each subsequent model included the unwanted sexual activity during childhood indicator, study center, and the variables shown in the respective columns.
bBlack non-Hispanic race/ethnicity was the reference group and does not appear in this table.
*P < .05; **P < .001.
