Several key metrics are used to quantify health data: - Incidence and Prevalence measure the occurrence of diseases within a population over a specified period. - Mortality rates indicate the frequency of deaths in a population. - Risk Ratios (RR) and Odds Ratios (OR) compare the risk of a certain event occurring in different groups. - Attributable Risk quantifies the contribution of a specific factor to the overall risk of a disease. - Years of Potential Life Lost (YPLL) measures the impact of premature death.
