Nonadjusted model adjusts for the following: no covariates were adjusted for. Minimally adjusted model: we only adjusted for sex, ethnicity, and age. Adjust II model adjusts for the following: sex, ethnicity, age, GCS, hypertension, angina; cardiovascular disease, cirrhosis, COPD, diabetes, stroke, TIA, BUN, anion gap, and WBC. GCS: Glasgow Coma Scale; COPD: chronic obstructive pulmonary disease; TIA: transient ischemia attack; BUN: blood urea nitrogen; WBC: white blood cell.
