aS100B levels at 72 h were collected in 19 patients from the thiamine group and 12 patients from the placebo group. bLactate levels at 72 h were collected in 16 patients from the thiamine group and 12 patients from the placebo group. Some patients either did not have a second or third lactate sampling or the results were missing or otherwise unavailable. Data are presented as medians (IQR) unless otherwise specified. CI, confidence interval; CPC, cerebral performance category; ICU, intensive care unit; IQR, interquartile range.
