The systematic review (SR), also referred to as a systematic review, is a comprehensive literature approach that systematically and comprehensively collects all published or published information about a specific clinical problem such as the cause, diagnosis, treatment, prognosis, care, etc. Unpublished clinical studies, using the principles and methods of rigorous evaluation of clinical epidemiology literature, screening out documents that meet the quality standards for qualitative or quantitative synthesis, concluded comprehensive and reliable conclusions. At the same time, with the advent of new clinical research results, systematic reviews should be updated in time to provide up-to-date knowledge and information as decision-making basis for clinical practice and research.
