: Given its retrospective design, this article does not contain any studies with human participants or animals performed by any of the authors. All data were collected and analyzed keeping anonymity, according to European laws on privacy. The study was approved by the Local Ethics Committee (Comitato Etico di Area Vasta Romagna) in February 2018. According to the Italian Authorisation of the Guarantor n.9/2016 and taking into account the logistic impossibility to reach out to all the women included in the study, given the large number of the sample, the investigators were exonerated from the request of informed consents.
