Inclusion and exclusion criteria (study type, language restrictions etc.)Inclusion criteria: Meta-analyzes; trials studies; clinical trials & updates of clinical trials; reviews; original articles; only studies/papers/journals written in English Exclusion criteria: Unpublished data from abstracts contained in volumes from various congresses or conferences; papers that were not in English
Selection process (who conducted the selection, whether it was conducted independently, how consensus was obtained, etc.)RB performed the search in the databases according to the presented criteria. If a study appears relevant by at least one reviewer - Bîrlă R and Constantin A - the full-text article has been retrieved and checked. The selection of full-text articles was made by two reviewers independently Constantin A and Bîrlă R. Assessing content validity required subjective judgment from the reviewers. The citation number was an important selection criterion. Differences were discussed and if consensus could not be reached between the two reviewers, we requested the consultation and recommendation of a third reviewer (Hoara P). The reference list from each selected article was screened for additional relevant information
