Criteria 3: specificity Hill suggested that associations are more likely to be causal when they are specific, meaning the exposure causes only one disease.

What is the difference between plausibility and coherence?

A subtle difference between coherence and plausibility is that plausibility asks: “Could you imagine a mechanism that, if it had truly operated (which could be counterfactual), would have produced results such as those observed in the data?” By contrast, coherence asks: “If you assume that the established theory is …
