  • Shown are the eGFR changes over the course of the study in the 52 study completers and in the 52 completers plus the 5 subjects who began dialysis during the study, for whom an end-of-study eGFR was imputed as 10 ml/min per 1.73 m2.

  • aP = 0.026 versus placebo and

  • bP < 0.006 versus placebo.
