Non-high-density lipoprotein cholesterol/high-density lipoprotein cholesterol is a predictor for cardiovascular mortality in patients with diabetes mellitus

Figure 4 Nomogram predicting cardiovascular mortality in patients with diabetes mellitus. A: Heart failure 1 indicates heart failure history, and 2 indicates no heart failure history. Race 1 indicates Mexican American, 2 indicates other Hispanic, 3 represents non-Hispanic white, 4 indicates non-Hispanic black, and 5 represents other ethnicities; Education (1-4 not shown in the nomogram but available online) 1 indicates less than 9^th grade, 2 indicates 9-11^th grade, 3 represents high school graduate, 4 indicates college, 5 represents college graduate or above, and 6 indicates unknown; B: Receiver operating characteristic curves of non-high-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio (NHHR) in predicting cardiovascular mortality for 60, 96, and 120 months in training cohort; C: Receiver operating characteristic curves of NHHR in predicting cardiovascular mortality for 60, 96, and 120 months in validation cohort. PIR: Poverty-income ratio; HF: Heart failure; NHHR: Non-high-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio; AUC: Area under the curve.
