Video notes:
Investigating cause of excess deaths
In 1965, English statistician Sir Austin Bradford Hill
Causal relationships
Strength
The larger the association, the more likely that it is causal
Consistency, (reproducibility)
Consistent findings, different persons in different places
Specificity
No other likely explanation
Temporality
The effect has to occur after the cause (often with a delay)
Biological gradient, (dose response relationship)
Greater exposure should lead to greater incidence of the effect
(or indeed lower incident of effect)
Plausibility
A plausible mechanism between cause and effect
Coherence
Between epidemiological and laboratory findings
Experiment
Occasionally it is possible to appeal to experimental evidence
Analogy
Analogies or similarities between the observed association and any other associations
Reversibility
May work if there is no permanent damage
