  1. The total value for NRI or IDI was computed compared with Clinical and HRCT added models to predict DARDS. Clinical model, APACHE II score, DIC score, and PaO2/FiO2 ratio; HRCT added model, APACHE II score, DIC score, PaO2/FiO2 ratio, and HRCT score. APACHE II, Acute Physiology and Chronic Health Evaluation II; CI, confidence interval; DIC, disseminated intravascular coagulation; HRCT, high-resolution computed tomography; IDI, integrated discrimination improvement; NRI, net reclassification improvement; SOFA, Sequential Organ Failure Assessment.
