- C-statistic and ∆C-statistic were used to interpret efficiency of the models and the incremental value of adding fibrinogen levels into original model. Original model included age, sex, body mass index, smoking, hypertension, family history of coronary artery disease, left ventricular ejection fraction, low density lipoprotein cholesterol, high lipoprotein cholesterol, Ln-transformed triglyceride, Ln-transformed high-sensitivity C-reactive protein, and creatinine. Original Model indicates the C-statistic for MACEs (cardiovascular mortality, non-fatal myocardial infarction, stroke and post-discharge unplanned revascularization)
