Note. Multivariate results depict a model with major- and minor interpersonal events adjusted for covariates (Interp SLE model) and a model with major- and minor non-interpersonal events plus covariates (Non-Interp SLE model).

OR = odds ratio. AOR = Adjusted odds ratio.
The 21 cases that experienced major interpersonal SLEs included divorce/separation (N=13), partner relationship problem (N=3), separation in another relationship (N=5), death of a family member or key network member (N=3), and physical assault victimization by an individual known to the subject (N=1). The events tally to > 21 because some cases experienced >1 major interpersonal SLE.
