Abstract
Decision-making in the medical field should be evidence-based. Evidence is presented in the form of articles; articles are written in the form of case reports, case series, cohorts, clinical trials, etc., depending on their statistical validity, and are primary evidence. Obviously, the more cases, the more valid the statistical results. Review articles use primary articles (the number of cases increases) and present a secondary article based on the available evidence with a higher degree of validity. 1-3, 5, 10, 11
