This study aimed at determining the prognostic values of RA for diabetic ketoacidosis (DKA).Methods: Data were obtained from Medical Information Mart for Intensive Care Database III V1.4 (MIMIC-III) and the RA calculated. Multivariate Cox regression analysis was performed to determine the correlation between RA and 90-day mortality or 365-day mortality.

The second outcome was the association between the incidence of DKA-related infections and RA.Results: For DKA patients in the ICU, RA was significantly correlated with 90-day mortality (HR: 2.1, 95% CI: 1.5, 3.0, p
