Explanation:
This question refers to Bradford Hill's criteria for causation. These are nine principles that Bradford Hill developed in order to allow researchers in epidemiology establish evidence of a causal relationship between a presumed cause and an observed effect. This criteria has been widely used in research. The criterion of strength, or effect size, indicates that a small association does not mean that there is not a causal effect, though the larger the association, the more likely that it is causal.
