Registry data analysis and reporting process. aA registry was excluded if it had been defunct for more than 5 years, had ≤300 participants, did not include data related to dialysis, was contained in and/or was redundant to another registry that was more appropriate for analysis. bReviewed databases not reported due to lack of available information (ie, insufficient data available through public sources and did not respond to queries for more information) included Israeli Society of Nephrology and Hypertension (The Official Israeli Nephrology Site), Madrid Registry of Renal Patients (although it did provide aggregate data to the Spanish Registry of Renal Patients), and Polish Registry of Renal Replacement Therapy in Children. The Scientific Registry of Transplant Recipients and Japan Renal Transplantation Registry were also excluded for focusing exclusively on transplant patients and providing no information on dialysis modalities.
