The titles and abstracts identified through the search strategy described above will be reviewed independently by 2 authors. To minimize data duplication due to multiple reporting, papers from the same author, organization, or country will be compared. For articles determined to be eligible based on the title or abstract, the full paper will be retrieved. Potentially relevant studies chosen by at least 1 author will be retrieved and the full text evaluated. Articles meeting the inclusion criteria will be assessed separately by 2 authors, and any disagreement will be resolved through discussion. In cases where agreement cannot be reached, the dispute will be resolved with the help of a third investigator. If authors are similar or incidence data are extracted from the same database, the study period will be assessed. If the study period overlaps, only the latest study will be included. A flow diagram for the search and selection process will be developed using the PRISMA guidelines.
