Erratum to: Pediatr Nephrol

DOI: 10.1007/s00467-014-2754-2

The name of the first author was rendered wrongly; his correct name is Osama Y. Safdar. The same error occurred in a previous erratum to this article (DOI: 10.1007/s00467-014-2784-9), which corrected the name of the fourth author, Neil Sebire.
