Abstract

The development of applications for obtaining interpretable results in a simple and summarized manner in multi-state models is a research field with great potential, namely in terms of using open source tools that can be easily implemented in biomedical applications. In this tutorial, we introduce MSM.app, an interactive web application using the Shiny package for the R language. In the following sections, we present the main functionalities of the MSM.app and an explanation of the outputs obtained for better understanding, independent of the statistical knowledge of users.
