Correction to: European Journal of Pediatrics https://doi.org/10.1007/s00431-021-04243-4

In the original published version of this article, the authors Doaa El Amrousy and Dina Shawky second affiliations should be “Tanta University Hospital, El Motasem Street No. 6, Tanta, Egypt” instead of “Clinical Pathology Department, Faculty of Medicine, Tanta University, Tanta, Egypt”.

The original article has been corrected.
