Drug-related covariates were not included in the final models because they might lie in the causal pathway linking place characteristics to perceived partner risk.
Bivariate models tested the relationship between each individual-level and census-tract level predictor and the outcome, controlling for the number of months since baseline and the number of months since relocation.
Because our measures of tract-level economic conditions were associated with our measures of tract-level violent crime rates, we ran two separate multivariable models, one for each of these predictors.
