Which option is NOT a Bradford Hill criterion?

Which option is NOT a Bradford Hill criterion?

• A. Temporality
• B. Consistency
• C. Plausibility
• D. Randomized control

Answer: (D)

The main idea here is understanding what Bradford Hill criteria are used for: they’re a set of considerations to help judge whether an observed association might be causal in epidemiology. Among the options, temporality, consistency, and plausibility are all named criteria. Randomized control, while a powerful study design for testing interventions, is not itself one of the Bradford Hill criteria. The Bradford Hill framework does include evidence from experiments as a criterion, and randomized trials can provide that experimental evidence, but the term “randomized control” isn’t listed as a criterion. So the option that isn’t a Bradford Hill criterion is the randomized control.
