Compliance with ethical standards
: As the present investigation involves data collected as a part of prior studies, no specific study protocol approval was needed, as all Institutional and Ethics Committees of each participating institution had already approved pertinent studies. Moreover, all participants in the original studies were informed of the study procedures and voluntarily signed informed consent forms prior to taking part in data collection. All data was blinded for the secondary analysis. The datasets from the different countries contain variables that are related to patient personal information that was deleted for the leader researcher before the computer scientist manages the data. The algorithm developed to create the ultimate database contains a filter to remove those columns from all the calculations; each user is identified by a randomly generated identification (ID) key that can be used by clinicians to find the specific person if needed.
: None.
