Odds ratio estimates with 95% confidence intervals for association with 30-day stroke or death from incremental logistic regression models: 1) univariate estimate of sex, 2) additional inclusion of demographic factors (age and race), 3) additional inclusion of artery characteristics (reference diameter and symptomatic status), and 4) additional inclusion of cardiovascular risk factors.
