Bradford Hill Causailty required groups x 9
- Temporal Relationship 2. Strength
- Dose Response 4. Consistency
- Plausability
- Consideration of Alternative Explanations
- Experiment 8. Specificity
- Coherance
Temporal Relationship
When the studied factor is present the disease factor is also always present.
Strength
The larger the size of the association the more likely factor A is to cause factor B
Dose Response
Increased exposure/dose increases the risk/response
Plausability
Current acceptance of an association between the causal factor and the disease
Consideration of Alternate Explanations
Consider/study multiple hypotheses before making conclusion on causal relationship
Experiment
The condition/disease can be altered or removed by removing/reducing the casual factor
Consistency
Results are consistent of the same study in a different area
Specificity
When a single reputed factor produces a specific effect
weakest of the Bradford Hill Causalities
Coherance
Area of research/hypothesis are compatable with existing theory and knowledge
When the studied factor is present the disease factor is also always present.
Temporal Relationship
The larger the size of the association the more likely factor A is to cause factor B
Strength
Increased exposure/dose increases the risk/response
Dose Response
Current acceptance of an association between the causal factor and the disease
Plausability
Consider/study multiple hypotheses before making conclusion on causal relationship
Consideration of Alternate Explanations
