Model 1 was adjusted for RR, SpO₂, liver disease, valvular disease, SAPS II score and SBP. Model 2 was adjusted for RR, SpO₂ and SOFA score. Model 3 was adjusted for RR, SpO₂, liver disease, valvular disease, SAPS II score, SBP and SOFA score. For 4-year mortality, only patients in the CareVue system who were followed for at least 4-year were analyzed. The bold values represents a P value < 0.05.
