Denominator of the percentage is the total number of patients.
^
Wilcoxon rank sum test is used to calculate the P-value.
**
Fisher exact.
^^
Chi-square test is used to calculate the P-value.
$
Multivariate logistic regression is used to calculate odds ratio and p-value after adjusting for patients’ baseline APACHE II, NUTRIC and SOFA scores.
