PCN60 FITTING DISTRIBUTIONS OF PARAMETRIC MODELS INTO NON-PARAMETRIC KAPLAN-MEIER CURVE: APPLICATION IN EXCEL AND COMPARISON OF DIFFERENT DATA RECREATION METHODS

To use Excel spreadsheet software to fit parametric survival distributions onto non-parametric Kaplan-Meier curve. The difference between Individual Patient Data (IPD) and survival data reconstructed in Excel and SAS was reviewed and the impact of those differences on economic evaluation results was assessed. Three sets of patient data on Overall Survival (OS) were compared using different elicitation methods: “Original” IPD, “Reconstructed SAS”...
