A lifetime horizon, as well as subsequent lines of therapy, was examined using open-source Amua 0.3.0 software. Base case analysis was performed using 10,000 first-order Monte Carlo simulations. Conditional probabilities were extracted from Kaplan-Meier curves from pivotal clinical trials using WebPlotDigitizer. Costs were estimated from RED BOOK and DFCI charge reporting in US Dollars ($) after inflation adjustment to 2022 and 3% discounting, and QALYs effects were measured using EQ-5D data from Hatswell et al.","dispersionType":"Standard Deviation","groups":[{"description":"All participants received one cycle of Lenalidomide (R), bortezomib (V) and dexamethasone (D) and then were randomized.
