Tests for trend include zero level of exposure (i.e., no child abuse).

No child abuse is reference group for all comparisons. All models of sexual abuse control for physical abuse, and vice versa.

^†Adjusted for age at baseline (centered at median age: 43 years) and parental education (<12, 12, 13–15, ≥16 years, missing/unknown).

β: Mean difference; Std Err: Standard error.
