  1. Data expressed as number (percentages) of total related variable and mean ± standard deviation. Student’s t test or the chi-square test was used, as appropriate. APACHE II and SOFA scores were estimated at ICU admission; sepsis and septic shock days denote the days post-ICU admission when sepsis and septic shock developed, respectively. APACHE, Acute Physiology and Chronic Health Evaluation; SOFA, Sequential Organ Failure Assessment.
