Adjusted odds ratios and 95% confidence interval of each respective quartile versus quartile 4 at duration ≥6 hours. Adjusted for age, diabetes, eGFR, inpatient/outpatient status, history of heart failure, percutaneous coronary intervention, fluid duration, and interaction between fluid volume and fluid duration.
