Model input parameters, Kaplan–Meier survival data, and R code for the cost-effectiveness analysis of nivolumab plus ipilimumab versus lenvatinib or sorafenib in unresectable hepatocellular carcinoma

This repository contains the model input parameters, reconstructed Kaplan–Meier survival data, and R code used for the cost-effectiveness analysis of nivolumab plus ipilimumab versus lenvatinib or sorafenib for unresectable hepatocellular carcinoma in China. The repository includes: Model input parameters used in the economic evaluation. Digitized Kaplan–Meier survival data derived from published clinical trial figures. R code used to construct the partitioned survival model and perform base-case and sensitivity analyses. Clinical efficacy and safety data were derived from the published CheckMate 9DW trial and publicly available literature.
