Criteria for the Occupational and/or Environmental-Relatedness of Disease: “Sir Bradford-Hill’s criteria for causation were developed for use in the field

of occupational medicine, but have been widely applied in other fields.9,10,11 These criteria serve as a general guide, and are not meant to be an inflexible list. Not all criteria must be fulfilled to establish scientific causation. The key criteria required to establish causation are commonly, (1) temporal relationship, (2) specificity, (3) biological plausibility, and (4) coherence.
