^aHazard ratios and p-values taken from multivariable Cox proportional hazards regression models adjusting for coma status, age, gender, race, APACHE II score, and Charlson co-morbidity index. ^bIntensive care unit (ICU) and hospital lengths of stay expressed as median days with interquartile ranges. ^cMortality expressed as n (%). CI, confidence interval; LOS, length of stay.
