*Data are percentages (n/N) with model estimated OR (95% CI) for the intervention and corresponding p value from logistic regression of abstinence on intervention adjusted for age, sex and insurance type stratification measures.
†Results presented are the range of least square mean type estimated percentages with range of estimate ORs for intervention and corresponding p values from the regression models for the abstinence outcome with lower AIC statistics.
