Corrigendum for the article Clin Nephrol. 2025; 103: 1-4.

Regarding the article by Fredrik Barth Brekke, Nanna von der Lippe, Ine Røed, Helga Gudmundsdottir, Martin Braaten, Espen Nordheim. Hyperbaric oxygen treatment in addition to conventional multidisciplinary care in patients with calciphylaxis. Clin Nephrol. 2025; 103: 1-4. doi: 10.5414/ CN111423, the authors would like to apologize for the error in Table 1 of page 2. Five patients were misclassified as CKD5 patients when established in dialysis. The correct number of patients in different CKD5 stage is corrected and marked in bold in revised Table 1 presented below. The same information is referred in the text in the following sentence: Ten patients (40%) had end-stage renal disease in need of renal replacement therapy at diagnosis (…). The correct number is 15 (60%). We have recalculated the statistics to make sure this has not affected the rest of our results including page 3 "there was no survival difference between patients on renal replacement therapy and patients not treated with renal replacement therapy" which is still correct. We are very sorry for any inconvenience due to these unfortunate errors.
