Beta-coefficients are based on linear regression models predicting log-transformed EBV antibody titers. All models are weighted, take into account complex sample design, and are adjusted for age, race, smoker in household at Wave 1, parental education, and parent occupation status at Wave 1.
Sample sizes vary slightly across models due to missing data on reports of physical and sexual abuse, and age at first onset of abuse. The sample sizes decrease in Model 3 because 178 respondents who reported physical abuse and 26 respondents who reported sexual abuse did not provide an age at first occurrence. In Model 4, the sample sizes reflect only individuals who reported abuse and provided an age at first occurrence.
R2 values reflect the full model (i.e., coefficients presented in the table, and covariates listed in Footnote 1).
