Kaplan-Meier survival curves for the elderly population that was classified according to CRP concentrations. a. In the successfully aging subgroup, the 1-year mortality rates were 1.6 % for ≤3 mg/L, 2.8 % for 3.1–10 mg/L, and 8.8 % for >10 mg/L. The differences between ≤3 mg/L and the other concentration ranges were significant (all p < 0.001). b. In the subgroup of individuals who suffered from aging-related diseases/disability, the 1-year mortality rates were 6.3 % for ≤3 mg/L, 10.3 % for 3.1–10 mg/L, and 19.2 % for >10 mg/L. The differences between ≤3 mg/L and other concentration ranges were significant (all p < 0.001)
