Variables (n = 297) | HR (95% CI) | p-value |
---|---|---|
Delta chloride for 24 hours (ΔCl24h) | 0.914 (0.866–0.966) | 0.001 |
Delta chloride for 48 hours (ΔCl48h) | 0.936 (0.888–0.987) | 0.014 |
Delta chloride for 72 hours (ΔCl72h) | 0.961 (0.910–1.014) | 0.258 |
Abbreviations; HR, hazard ratio; CI, confidence interval. Definitions; The 24 hour delta chloride concentration (ΔCl24h) (mEq/L) was calculated by the following formula: [Cl24h] − [Clat baseline], where Cl24h is the chloride concentration at 24 hour, and Clat baseline is the baseline chloride concentration. The 48 hour delta chloride concentration (ΔCl48h) (mEq/L) was calculated by the following formula: [Cl48h] − [Clat baseline], where Cl48h is the chloride concentration at 48 hour, and Clat baseline is the baseline chloride concentration. The 72 hour delta chloride concentration (ΔCl72h) (mEq/L) was calculated by the following formula: [Cl72h] − [Clat baseline], where Cl72h is the chloride concentration at 72 hour, and Clat baseline is the baseline chloride concentration.
