B: beta co-efficient of linear mixed effect model. Models adjusted for age at baseline, employment, education, current smoking, current alcohol use and baseline rape-exposure. CA, childhood abuse. P-interact (CA*baseline-rape-exposed): p-value for the interaction terms, child abuse*baseline-rape-exposed, in each exposure type and outcome examined
