  1. General admission characteristics and mortality of patients with sepsis with Charlson’s Comorbidity Index zero at ICU admission and reciprocal controls with Charlson’s Comorbidity Index zero at the index date. Estimated Mortality Rate (EMR) was calculated using acute Acute Physiology And Chronic Health Evaluation II (APACHE II) for patients included before 2013 or Simplified Acute Physiology Score III (SAPS III) from 2013 onwards, representing the predicted probability of in-hospital death based on illness severity at ICU admission. Data presented as median (IQR) for continuous measures, and % (n) for categorical measures. n/a, not applicable.
