Table 5

Time to RRT initiation, predialysis urea and patient cohort survival from Bouman et al. [89].

	Early high volume Group (𝑛=35)	Early low volume Group (𝑛=35)	Late low volume Group (𝑛=30)
Time between inclusion and first RRT (hrs)	6.0 (3.0–9.7)	7.0 (5.0–10.0)	41.8 (21.4–72.0)^a
Predialysis urea before first RRT (mmol/L)	16.3 (13.7–20.6)	17.1 (14.4–23.5)	37.4 (22.0–41.4)^a
Survival (%)^b	74.3	68.8	75.0

Data presented as median and interquartile ranges.
^a𝑃<.001 between late low volume group and early groups.
^b𝑃=.8 between groups.
