Which of Hill's viewpoints emphasizes the sequence of events?

Temporality is the viewpoint of Hill that focuses specifically on the sequence of events. In epidemiological research, it refers to the notion that the exposure to a causal agent must precede the occurrence of the outcome for a causal relationship to be established. This concept is crucial because it helps clarify that if an exposure leads to an effect, the timeline must show that the exposure occurred first. In establishing causation, understanding the order of events allows researchers to infer relationships and make informed conclusions about potential risks and outcomes in public health contexts.

To elaborate further, strength pertains more to the strength of the association between exposure and outcome; coherence involves the consistency and plausibility of the observed association with existing knowledge; and experiment refers to the idea that evidence from experimental studies can support causal inferences. Each of these viewpoints plays an important role in assessing causality, but temporality is uniquely focused on the chronological order of events.
