A Comparison of Different Analysis Methods for Reconstructed Survival Data to Inform Cost‑Effectiveness Analysis

The aim of this study was to use Microsoft Excel spreadsheet software to fit parametric survival distributions. We also explain the differences between individual patient data (IPD) and survival data reconstructed in Excel and SAS. Three sets of patient data on overall survival were compared using different methods: ‘original’ IPD, ‘reconstructed SAS’, and ‘reconstructed Excel’. The best-fit distribution was selected using visual observation,...
