Baseline characteristics by incident primary combined nonfatal and fatal endpoint (p-value versus no event group).

Please note that because of the design structure of the trial—recruiting more participants with hypertension/smokers and diabetes (and women) into the low risk primary prevention group—the significance or nonsignificance of univariate comparisons in this table could be potentially misleading. p-Values for continuous variables are from two-sample t-test and for categorical variables from chi-squared test.aValues are geometric means (SD) calculated from the log-transformed distribution and the (p-value).SD, standard deviation; TIA, transient ischemic attack.
