Cochrane produces systematic reviews because they are the most reliable way to find out if a particular intervention or test is effective.
When we do a systematic review, we carefully examine all of the scientific research in order to answer a particular question – for example, ‘Does treatment X help people with disease Y?’ – and then we work out what the overall effect is. We use sophisticated statistical methods to combine and compare several studies, sometimes hundreds, making our reviews more reliable than individual studies.
