Hourly time course of fractional excretion of sodium (FeNa+, dark bar) and urinary sodium concentration (Na+, open bar) before and after the administration of an intravenous bolus of furosemide in the overall study population (single-dose group, group n = 39). Data are expressed as median value, interquartile range, and 5° and 95° percentile range. Time 0 (baseline) denotes the time of furosemide administration. One-way ANOVA for repeated measurements was performed (P < 0.001 for time effect; *P < 0.001 vs. baseline, time 0)
