Can anyone guide me where I can find and understand the GRADE approach method for my ongoing systematic review? I referred to Cochrane and it's way too complicated to understand.
It gives level of evidence/certainty for the included studies of the SR (v low, low, mod, high). This level decreases a level with presence of Risk of bias, Imprecision, Inconsistency, Indirectness, or Publication bias and increases with presence of Large magnitude of effect, Dose-response gradient, or All residual confounding would decrease magnitude of effect (in situations with an effect).
