We tried to identify all the factors affecting the trauma and design the key words of the paper based on them. Search and data extraction were based on the PRISMA checklist. All the extracted articles were imported into the EndNote X۸ software and the studies that were extracted several times were deleted. Then, the data extraction and quality analysis of the articles was done by two researchers separately and the data was reported through a descriptive report and use of systematic review tables.
