Figure 2

(a) Nomogram showing results of the diagnostic model using gender, age, neutrophil, RDW, LDH, and HbA1c. Each diagnostic factor corresponded to a score, and the total score of an individual patient was obtained by adding the scores of the individual factors, and a straight line was drawn on the axis of the total score to predict the risk of coexisting cardiovascular disease in COPD. (b) The ROC curves for the diagnostic nomogram. (c) The calibration curves of the diagnostic nomogram.
