Figure 5: Comparison of urine volume: A compares the total urine output in 48 h in patients with ejection fraction<30%, a systolic blood pressure of<110 mmHg at the start of treatment, and an eGFR of<30 ml/min/1.73 m2. B shows the relationship between left ventricle ejection fraction and total urine output up to 48 h after the start of treatment.
