All-cause mortality at 60 days as a function of days managed using intermittent hemodialysis. The time in the intermittent hemodialysis (IHD) phase was defined as the number of days from the first IHD treatment or from the first day after continuous renal replacement therapy (CRRT) or sustained low-efficiency dialysis (SLED) was discontinued until the last day of IHD treatment, the last day before initiation of CRRT or SLED, or the discontinuation of study therapy. Days with IHD and with either CRRT or SLED were counted as in the IHD phase. The percentage of days managed using IHD was calculated by dividing the number of days in the IHD phase by the total number of days of study therapy.
