To the Editor: Dr Lee and colleagues1 reported the development and validation of a 12-item prognostic index for 4-year mortality in 2 cohorts of persons aged 50 through 85 years. The risk index has excellent discriminative power, indicated by a c statistic of 0.82 in the validation cohort. The authors conclude that the prognostic index can stratify patients 50 years or older into high-, intermediate-, and low-risk groups that may be useful for clinical decision making.
