p values were calculated using Fisher exact test for frequency comparisons of categorical variables and Mann-Whitney U test for two-group comparisons of continuous variables. All statistical tests were two-tailed. Significant values are highlighted in bold. SAH = subarachnoid hemorrhage; NCI = neurocardiogenic injury; SD = standard deviation.
