    Snippet: Continuous variables are presented as the median and interquartile range. Categorical variables are presented as percentages. Continuous variables were compared using a Mann-Whitney U test. Categorical variables were compared using a chi-square or Fisher exact test. The optimal cut-off values for potential predictors of ICU mortality were selected using either the median value or locally weighted scatterplot smoothing curves 14 , as appropriate. .....
    Document: Continuous variables are presented as the median and interquartile range. Categorical variables are presented as percentages. Continuous variables were compared using a Mann-Whitney U test. Categorical variables were compared using a chi-square or Fisher exact test. The optimal cut-off values for potential predictors of ICU mortality were selected using either the median value or locally weighted scatterplot smoothing curves 14 , as appropriate. Binary logistic regression analysis was performed to identify factors predicting ICU mortality. Variables with p-values of <0.20 in the univariate analysis were included in the multivariate analysis.
