Bradford Hill criteria

In 1965, Sir Austin Bradford-Hill (1897-1991), a British medical statistician, established nine widely used criteria to determine the strength of an association between a disease and its supposed causative agent. These criteria are used as a way of determining the causal link between a specific factor (e.g., cigarette smoking) and a disease (such as cancer).
