Observing the unobserved confounding through its effects: toward randomized trial-like estimates from real-world survival data

ArXi:2604.12137v1 Announce Type: cross Background: Randomized controlled trials (RCTs) are costly, time-consuming, and often infeasible, while treatment-effect estimation from observational data is limited by unobserved confounding. Methods: We developed a three-step framework to address unobserved confounding in observational survival data.
