The difference between systematic review and traditional review is that

The difference between systematic review and traditional review: 1. Different clinical problems; 2. The sources and collection steps of documents are different; 3. Different literature screening criteria; 4. Different quality evaluation; 5. Synthesis of different data; 6. The conclusion is different. The difference between extended data system review and traditional review: 1. Clinical problems are different. Traditional review involves a wide range of topics, while systematic review aims at a specific clinical problem; 2. The sources and collection steps of documents are different. The traditional review is based on the author's wishes, and some documents he is interested in can be evaluated selectively, while the systematic review emphasizes the unified retrieval strategy, so as to carry out comprehensive and systematic retrieval; 3. Different literature screening criteria. Traditional reviews are unmarked and selected according to the author's interests, while systematic reviews must specify unified literature screening criteria; 4. Different quality evaluation. Traditional reviews usually don't evaluate the documents cited by us, but systematic reviews require strict or critical evaluation of the documents included in the evaluation; 5. Data synthesis is different. The traditional review is mainly qualitative description, while the systematic review is to quantitatively synthesize the data of these single studies by meta-analysis method and get a combined result; 6. The conclusion is different. The conclusion of traditional review often depends on the author's own point of view or some clinical documents, while systematic review is not based on the author's point of view, but on the result of evaluating evidence, which is relatively objective.
