  Fig. 1. Diuretic efficiency by BAN-ADHF score category. Box plots of diuretic efficiency (mL urine output per mg intravenous furosemide equivalent) at (A) 24 h and (B) 72 h across low- (≤7), moderate- (8–12), and high- (≥13) score categories. Boxes denote the median (labeled) and interquartile range, whiskers the 1.5 × IQR range, and overlaid points individual patients; the number of patients per category is shown below each box. Median 24-hour efficiency fell 4.2-fold from the low- to the high-score category (Kruskal–Wallis p < 0.001). Score categories are exploratory (derived and evaluated in the same cohort). For visual clarity the y-axis is truncated at 250 mL/mg; 8 (24-hour) and 28 (72-hour) values above this range are not displayed but are included in all statistics.
