Probabilistic Markov Model for Cost-Effectiveness Analysis of FEVAR versus OSR versus Observation

We aimed to develop a probabilistic Markov model and conduct a cost-effectiveness analysis of fenestrated endovascular aneurysm repair (FEVAR) versus open surgical repair (OSR) versus observation of complex abdominal aortic aneurysms (cAAA). This repository contains: 1. An Excel file named "Model" with the probabilistic Markov model and its Visual Basic script (software code). 2. A word document named "Model Description" to guide the reader in interpreting and running the Markov model. 3. A word document named "References" to list references used for model parameters. 4. A word document named "Supplemental Data" containing supplemental results of cost-effectiveness analysis for reviewers.
