Figure 3.

The graph displays the percent of treatments greater than 4.5 sessions/week and more than 27 hours/week over the preceding 6 or 12 months in subjects randomized to either conventional or more frequent-long hemodialysis.

Deaths prior to transplant are indicated by the numbers at the bottom of the plot; 1 indicates deaths classified as not occurring on frequent-long by both 6 and 12 month moving averages; 2 indicates deaths classified as occurring on frequent-long by the 12-month moving average only; 3 indicates deaths classified as occurring on frequent-long by both 6 and 12-month moving averages.

Numbers in black refer to deaths in subjects randomized to the nocturnal arm and numbers in gray refer to deaths in subjects randomized to the conventional arm. No deaths were classified as occurring on frequent-long by the 6-month but not the 12-month moving average.

Of the 18 deaths which occurred prior to kidney transplantation, two are not shown: one death that occurred during month 70 for a subject not following a frequent-long schedule and an additional death for a patient with no follow-up visits. Both these patients had been randomized to the conventional hemodialysis group.
