Researchers have developed a new statistical framework called the Bayesian fusion forest to estimate the effects of treatments on survival outcomes. This method combines data from randomized controlled trials with real-world data, relaxing strict assumptions about the real-world data's unconfoundedness. The framework models survival time using a Bayesian tree ensemble prior, allowing for shared baseline prognoses across data sources while capturing between-source heterogeneity. Applied to HIV treatment data, the fusion approach identified a benefit for nearly all patients, a finding inconclusive with trial data alone. AI
