Coefficient for cirrhosis under different multiple regression models
| Model | Cirrhosis b (95% CI) | ∆ b |
| Univariable regression on cirrhosis | −0.49 (−0.67 to −0.32) | |
| Model 1: Adjusted for age, pretreatment K+, log creatinine, active cancer, beta-blocker use, and cotreatments (n=463)* | −0.48 (−0.64 to −0.31) | +2.8%† |
| Model 2: Adjusted for Model 1 covariates and the pretreatment pH levels (n=463)‡ | −0.48 (−0.64 to −0.32) | −0.3%§ |
| Model 3: Sensitivity analysis, Model 1 covariates excluding patients who received repeat insulin-glucose treatment (n=370) | −0.42 (−0.61 to −0.23) | +12.1%§ |
| Model 4: Sensitivity analysis, Model 2 covariates excluding patients who received repeat insulin-glucose treatment (n=370) | −0.44 (−0.63 to −0.25) | +8.8%¶ |
*Intravenous furosemide excluded from cotreatment list as it was balanced in both groups and not statistically significant in the model.
