Although we did not execute a systematic literature search to supply our checklist, which is indeed a limitation of our energy, PRISMA was designed using an proof centered method Every time doable. Checklist items were being integrated if there was evidence that not reporting the merchandise was connected with increased hazard of bias, or where by it was distinct that information was important to appraise the reliability of an evaluation.

At present the Cochrane Methodology Sign up has greater than eleven 000 data pertaining to the conduct and reporting of systematic reviews and various evaluations of wellness and social care.
