Sir Austin Bradford Hill proposed nine principles to guide the determination of causality in epidemiology. These principles are:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Strength of association<\/strong>: The stronger the association between an exposure and an outcome, the more likely it is causal. A large effect size supports a causal link.<\/li>\n\n\n\n<li><strong>Consistency of association<\/strong>: This refers to the repeated observation of the association in different studies, settings, and populations. Consistent findings strengthen the likelihood that the relationship is causal.<\/li>\n\n\n\n<li><strong>Biological plausibility<\/strong>: This guideline suggests that the relationship between exposure and outcome should make sense biologically. There should be a known mechanism that can explain how the exposure leads to the outcome.<\/li>\n\n\n\n<li><strong>Temporality<\/strong>: The cause must precede the effect in time. This is a fundamental criterion for establishing causality, as an effect cannot occur before its cause.<\/li>\n\n\n\n<li><strong>Specificity<\/strong>: The more specific the association (i.e., a single cause leads to a single effect), the stronger the argument for causality.<\/li>\n\n\n\n<li><strong>Dose-response relationship<\/strong>: If an increase in exposure leads to an increase in the effect (or vice versa), this suggests causality.<\/li>\n\n\n\n<li><strong>Reversibility<\/strong>: If removing or reducing the exposure leads to a decrease in the effect, it provides evidence of causality.<\/li>\n\n\n\n<li><strong>Coherence<\/strong>: The relationship should be consistent with known facts about the disease or phenomenon, fitting within the broader body of scientific knowledge.<\/li>\n\n\n\n<li><strong>Experiment<\/strong>: The ability to demonstrate causality through experimental evidence (e.g., clinical trials) can be a strong argument for a causal link.<\/li>\n<\/ol>\n\n\n\n<p><strong>Sample size<\/strong>, on the other hand, is a methodological consideration rather than a causal guideline. While a larger sample size can increase the precision and reliability of a study, it does not provide direct evidence for a causal relationship. A small sample size can still yield valid causal conclusions, though it may limit the generalizability of the findings.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following is not a causal guideline? sample size biological plausibility consistency of association strength of association The correct answer and explanation is: The correct answer is sample size.
