c
Chi-squared tests of association
d
Univariable logistic regression for independent variables significant at p≤.1
e
Final logistic regression model, showing significant predictors of abstinence after controlling for contact interval (as a continuous variable) and condom use at baseline visit
f
The variables “POC TV positive” and “Belief that STI was positive” were highly correlated so separate models were developed, please see text.
