Notes: models 1, 2, and 3 were derived from Cox proportional hazards regression models. (a) Model 1 covariates were adjusted for nothing; (b) model 2 covariates were adjusted for age, sex, and race; (c) model 3 covariates were adjusted for age, sex, race, heart rate, SBP, DBP, respiratory rate, temperature, SPO2, SOFA, chloride, and AF.
