Values are means ± SD or n (%); n, number of subjects. One-way ANOVA (non-CAD, top, P value) or two-tailed independent samples t test [male vs. female <40 yr (*) or ≥40 yr (‡); CAD males vs. females] was used for comparing age and BMI between groups. Pearson’s χ2 test was used for all remaining categorical variables. Boldface indicates significance.
