Survivor/nonsurvivor: septic patient alive/dead 28 days after admission to medical intensive care unit.
APACHE II: Acute Physiology and Chronic Health Evaluation II.
Continuous data are presented as Mean ± SD.
Categorical data are presented as number of patients (percentages).
Values have been calculated using Chi-square test and Mann-Whitney 𝑈 test.
^aCalculated using Fisher’s exact test.
^bValues total more than 100%, since patients could have more than one condition.
𝑃<0.05 statistically significant.
NS: not significant.
