  1. C 0 and D 0: inclusion visits for subjects of the control and dialysis groups respectively; D 1–7 follow-up visits for the dialysis group. The patients were included progressively and for this reason, even if the drop out was only due to deaths, the number of patients decreases from visit 1 to visit 7.
