The Bradford Hill criteria, otherwise known as Hill's criteria for causation, are a group of minimal conditions necessary to provide adequate evidence of a causal relationship between an incidence and a consequence, established by the English epidemiologist Sir Austin Bradford Hill (1897–1991) in 1965.
The list of the criteria is as follows:
1.Strength of association (odds ratio)
4.Temporal relationship (temporality) - not heuristic; factually necessary for cause to precede consequence
5.Biological gradient (dose-response relationship)
6.Plausibility (biological plausibility)
9.Analogy (consideration of alternate explanations)
How many of these do we have, between CCSVI and MS?
