Absolute and relative prognostic values

Defines absolute survival (e.g., median or 5-year survival) and relative survival (e.g., survival of a population with a disease compared to the survival of a population without the disease) and how these measures of survival are different. Learning objectives 0:00 Define absolute survival and interpret common clinical metrics, such as the 5-year survival rate and median survival time. 1:00 Explain the concept of relative survival by contrasting observed patient survival with the expected survival of a matched general population. 1:52 Differentiate between absolute and relative survival values to determine which measure is most appropriate when disease-specific data is unavailable.
