Play an AI-generated podcast conversation about this lesson

What is the primary assumption of the strength of association guideline in Hill's criteria for assessing causation?

Associations are only causal if they are observed in a single population.

Small associations are always indicative of causality.

Stronger associations are more indicative of the exposure being causal. (correct)

Biased studies always produce weak associations.

What is the primary goal of Hill's guideline on consistency?

To identify the specific cause of a disease.

To demonstrate that an association is observed across different circumstances. (correct)

To determine the biological gradient of a disease.

To establish a temporal relationship between exposure and outcome.

Which of the following is a modern critique of the consistency guideline?

Sometimes there are good reasons why study results differ. (correct)

All studies must be conducted in the same population.

Studies with different results are always biased.

There are never good reasons why study results differ.
