Adjusted estimates are differences in events per person-year between treatment and control groups estimated by Poisson regression with explanatory variables listed below and survival time as the exposure variable.
Adjusted estimates are differences in probability of the event between treatment and control groups estimated by logistic regression. Explanatory variables included baseline values for race; Hispanic ethnicity; gender; language; education; New York Heart Association class; and indicators for diabetes, chronic pulmonary disease, ischemic heart disease, and recruitment site.
Values in parentheses are the numbers of patients who responded. Adjusted estimates are expected values from mixed models. Independent variables include the explanatory variables listed above, as well as linear time and its square, treatment, and treatment–time interactions.
