Fig. 2From: Incorporating individual historical controls and aggregate treatment effect estimates into a Bayesian survival trial: a simulation studyImpact of α0 and ω on the operating characteristics for scenarios S1 to S4. A Weibull distribution is used for the historical and new data, with \( {\boldsymbol{\sigma}}_{\boldsymbol{H}}^{\mathbf{2}} \) equivalent to 329 events. We assume that historical and new control arm are commensurateBack to article page
