Kaplan-Meier curves for cumulative incidence of type 2 diabetes (cumulative incidence ± 1 SE) in 272 NGT subjects with WBC
in the upper and lower tertile, after adjustment for age, sex, and percent body fat. The number of events was 22 in the upper
tertile, 21 in the middle tertile, and 11 in the lower tertile. For clarity, only the curves for the upper and the lower tertile
are shown. The curve for the middle tertile (not shown) lays between the other two.
