Table 4 Reclassification among people who do or do not experience an ASVD hospitalization or death during 10-year of follow

From: Estimated glomerular filtration rate as an independent predictor of atherosclerotic vascular disease in older women

  Framingham predicted risk with eGFR by MDRD equation  
Framingham predicted risk without eGFR < 15% 15-30% ≥ 30% Reclassified higher risk Reclassified lower risk Correctly reclassified

  1. Net reclassification improvement (NRI) = 5.9% P = 0.018, IDI = 0.010 ± 0.003, P < 0.001. Framingham risk factors included age, body mass index, smoking, systolic blood pressure and diabetes. ASVD indicates atherosclerotic vascular disease; eGFR estimated glomerular filtration rate and MDRD Modification of Diet in Renal Disease equation.
