Survival results after adjusting, using a multivariable survival Cox model accounting for physician cluster effects, for diastolic blood pressure, age, gender, self-reported measures of adherence, and cardiovascular risk profile, were not statistically significant either (HR 0.97; 95% CI 0.67, 1.39)
