AIC = Akaike information criterion; BIC = Bayesian information criterion; IDI = integrated discrimination improvement; rIDI = relative integrated discrimination improvement; NRI = net reclassification improvement (category free); other abbreviations as in Tables 1 and 2.
↵⁎ Only significant predictors of CHF are shown. However, all models are also adjusted for ethnicity, antihypertensive medication use, total cholesterol, HDL-cholesterol, current smoking, heart rate, and estimated GFR. All HRs are standardized.
↵† Larger decreases (changes with negative sign) indicate a larger improvement in model fit.
↵‡ Larger increases indicate a larger improvement in performance in reclassification or discrimination.
↵§ p < 0.05.
↵∥ Improvements in model performance when both SBP and DBP are added to a model containing all other variables contained in the full model.
