Age is presented both as median age and categorized as <60, 60–74 and ≥75. Ethnicity is presented as % White. NKF recovery was assigned in the following three settings: where a treating centre provided a timeline code indicating recovery of NKF and KRT was not restarted within 90 days (irrespective of date of death), where an individual discontinued dialysis and was alive without restarting KRT 90 days later and where an individual was lost to follow-up but was shown to be alive 90 days after dialysis initiation. All other individuals were assumed to not have recovered NKF. *Percentages in those with ethnicity data. **Individuals lost to follow-up, but alive at day 90 were presumed to be alive following recovery of NKF.
