Flow diagrams illustrating the similarities and differences between Classic Systematic Review (SR) (a) and Classic Weight of Evidence (WoE) (b). Classic SR methodically searches, screens, evaluates bias, and extracts data from relevant studies of the same type and combines them by meta-analysis. Classic WoE uses all relevant study types and inference by weight of evidence using Hill’s (1965) or equivalent considerations.
