Kaplan-Meier curves showing cumulative patient survival between early and late dialysis groups defined by RIFLE classification. The brown solid line corresponds to the early dialysis group (RIFLE-0 and -I, n = 51), and the black dashed line corresponds to the late dialysis group (RIFLE-R and -F, n = 47). RIFLE, Risk, Injury, Failure, Loss of function, End-stage kidney disease; RRT, renal replacement therapy. Reprinted from [3].
