In analytical epidemiology, time is crucial for establishing temporal relationships between exposures and outcomes. Key concepts include:
Latency period: The time between exposure to a risk factor and the manifestation of the disease. Incubation period: The time between exposure to an infectious agent and the appearance of symptoms. Study designs: Cohort studies follow participants over time to observe the development of outcomes, while case-control studies look back in time to identify previous exposures.
