Competing interest

: None of the authors have any competing interests. The authors do not have any commercial or collaborative relationships that could be construed as biased or inappropriate. The decision to submit the paper for publication was not influenced by any funding body.

: Ethical approval was obtained from The IDF medical corps ethics committee (reference number 1175–2012). The IDF ethics committee waived the need for formal informed consent since actual patient files were not reviewed in this study but rather computerized data only.

: Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
