WebFeb 26, 2024 · Two mixture cure models were developed to illustrate (1) an "uninformed" approach where the cure fraction is estimated from trial data and (2) an “informed” approach where the cure fraction is obtained from an external source (e.g., real-world data) used as an input to the model. WebJan 1, 2008 · Mixture cure models (MCMs) have been widely used to analyze survival data with a cure fraction. The MCMs postulate that a fraction of the patients are cured from the disease and that the failure time for the uncured patients follows a proper survival distribution, referred to as latency distribution.
