Why is systematic review the highest level of evidence?

In the Pyramid of Evidence Based Medicine, a Systematic Review of Randomized Control Trials is located at the top; because so many studies are used, it greatly reduces bias. One of the first steps researchers take is to conduct an organized search to find and collect all of the relevant studies. This part is key.

What is the strongest level of evidence?

Both systems place randomized controlled trials (RCT) at the highest level and case series or expert opinions at the lowest level. The hierarchies rank studies according to the probability of bias. RCTs are given the highest level because they are designed to be unbiased and have less risk of systematic errors.

Are systematic reviews good?
