Multivariable logistic regression testing for an association between hyperchloremia and complicated course (CC) or mortality, after adjusting for PERSEVERE-based risk of mortality.

Outcome	Variable	OR (95% CI)	P value
Complicated Course	Minimum Chloride ≥110 mmol/L	1.9 (1.0–3.4)	0.047
	Maximum Chloride ≥110 mmol/L	0.9 (0.6–1.3)	0.572
	Mean Chloride ≥110 mmol/L	1.3 (0.8–2.0)	0.223
Mortality	Minimum Chloride ≥110 mmol/L	4.1 (2.1–8.1)	<0.001
	Maximum Chloride ≥110 mmol/L	1.3 (0.7–2.1)	0.384
	Mean Chloride ≥110 mmol/L	2.3 (1.3–3.9)	0.003
