Significant differences between groups were detected by means of χ2 test for categorical variables, and by the Student's t-test or Mann-Whitney test for continuous variables, as appropriate. Univariate analysis of variance (ANCOVA), adjusted for age and gender was used to compare hospital length of stay and in-hospital mortality between the two groups.
Significant p values are highlighted in bold.
