Development and validation of a clinical factor-based nomogram for predicting imaging-defined cardiopulmonary abnormality risk in an asymptomatic screening population

Figure 2 Nomogram of the comprehensive clinical prediction model, including independent risk factors: Sex, age, Body mass index, metabolic status, and smoking history. Sex (1 = male, 0 = female); metabolic status (1 = abnormal metabolic status, 0 = normal metabolic status); smoking history [0 = non-smoker, 1 = mild (smoking index ≤ 200), 2 = moderate (200 < smoking index < 400), 3 = heavy (smoking index ≥ 400)]. BMI: Body mass index.
