Ethics approval and consent to participate
: The Italian legislation identifies the National AIDS Registry at Istituto Superiore di Sanità and the National Register of Causes of Death at Istituto Nazionale di Statistica, as collectors of personal data for surveillance purposes without explicit individual consent. The approval of a research ethic committee is not required, since this study is a descriptive analysis of individual data without any direct or indirect intervention on patients (Decreto del Presidente del Consiglio dei Ministri, 3/3/2017, Identificazione dei sistemi di sorveglianza e dei registri di mortalità, di tumori e di altre patologie, 17A03142, GU Serie Generale n.109 del 12-05-2017, Available at: ExternalRef removed, last access: 25/06/2018). The datasets were used under license for the current study only, given the inclusion of this investigation in the Italian National Statistical Plan, after clearance of the Italian Data Protection Authority.
