Notes: All data (except for AUCs) are reported as odds ratios (ORs) are adjusted for age, gender, center, and primary diagnosis. AUC = area under the curve; CI = confidence intervals; MPI = Multidimensional Prognostic Index.
†AUCs were related to model with MPI in category.
‡75 participants were dead during hospitalization and 61 were lost at the follow-up.
