FENa(%) and FEUrea(%) at the different time points in AKIuo. (A) U-shaped form of FENa over the different AKIuo classes (N, no AKI; R, Risk; I, Injury; and F, Failure; (P = 0.07, 0.016, and 0.01 at d0t0, d0t4, and d1, respectively). (B) Decreasing trend in FEUrea(%) across AKIuo classes at the different time points with persistently low FEUrea(%) in RIFLE F class at the three time points (P = 0.029; P = 0.001; and P = 0.098).
