Figure 1

(a) Boxplot of the fractional excretion of sodium (FeNa) in the overall study population according to renal function. The dotted line represents FeNa of 1% (P = 0.04). (b) Boxplot of the fractional excretion of urea (FeUrea) in the overall study population according to renal function. The dotted line represents FeUrea of 35% (P = 0.12). (c) Boxplot of the urine/plasma (U/P) urea ratio in the overall study population according to renal function. The dotted line represents a U/P urea ratio of 10 (P < 0.0001).
