  • *Adjusted for age, gender, Hb and CKD-EPI eGFR, Charlson Index score (a validated method of weighting chronic medical conditions (the score for diabetes was excluded as diabetes is included as a separate variable)), with admission unit as a random effect.

  • ICU, intensive care unit; IRR, incidence rate ratio, applicable to continuous variables; OR, incidence ratio, applicable to categorical variables, using patients with no diabetes as a reference.
