For continuous variables mean (SD) is displayed. For discrete variables, percent is displayed. Results based on patients who received some of study medications. Patients who received none of the medications were excluded. These analyses include the 293 patients who received the first syringe for the magnesium vs placebo comparison and 269 who received both syringes for the remaining comparisons, except as indicated for the blood pressure measurements. For analyses on days to death, awakening was not a censoring event.
CPR = cardiopulmonary resuscitation; SBP = systolic blood pressure.
