Data are presented as no. (%) unless otherwise indicated.

Abbreviations: APACHE, acute physiology and chronic health evaluation; ICU, intensive care unit; IQR, interquartile range.

a Analysis using Chi-square test or Mann-Whitney U test.

b Matching variables.

c ‘Initial ICU admission’ means an intensive care unit admission at the beginning of hospitalization. ‘Initial altered mentation’ means altered mentation between onset and admission. Missing data for variables such as initial APACHE II score (n = unmatched non-steroid group 15, unmatched steroid group 1), initial ICU admission (unmatched non-steroid 2), initial altered mentation (unmatched non-steroid group 6, unmatched steroid group 2), initial GCS score (unmatched non-steroid group 12, unmatched steroid group 6, matched non-steroid group 4, matched steroid group 4), and complications (unmatched non-steroid group 1).
