Propensity score matching (1:2 ratio) was conducted in CHF\u2010T2DM patients to eliminate the differences in demographics, comorbidity, and the severity of diabetes.

Multivariable conditional logistic regression revealed a significant association between insulin therapy during hospitalization and in\u2010hospital death in both cohorts (MIMIC: OR, 1.37 [95% CI, 1.14\u20131.63]; TJHFIT: OR, 2.56 [95% CI, 1.53\u20134.27]).

RCS revealed both ePVS and \u0394ePVS were associated with in\u2010hospital death in a nonlinear fashion.
