Evaluate Cutpoints

an user-friendly application for survival analysis

 

INTRODUCTION

Evaluate Cutpoints is an user-friendly application developed in R environment for optimization of cutpoints in biomedical research. Many recent studies are focused on identification of biomarker that can serve as a prognostic factor and further corresponding relationship with clinical effect. As a result of increasing interest in use of dichotomization of continuous variables involving clinical or epidemiological data (gene expression, biomarkers, biochemical parameters, etc.) there is a large demand for cutpoint determination tools. Evaluate Cutpoints offers wide range of statistical methods for stratification of input population into two or three groups based on cutpoint determined from continuous variables as well as corresponding graphical output, which may be used in scientific publications.

 

TERMS OF USE

Evaluate Cutpoints is freely available application based on R scripts. It comes with no warranty. User can present and use arising results, however we kindly ask you to cite publication supporting the application.

NEW FEATURE:

AUTOMATIC MULTIPLE ANALYSES MODE

EvaluateCutpoints in the user-friendly graphical user interface (GUI) form allows to manually perform the analyses on single biomarkers. If your aim is to automatically analyze multiple biomarkers, please use the ready-to-use R package available at GitHub repository https://github.com/mogluszka/evaluateCutpoints. Installation guide and user's vignette are also available therein.

 

TROUBLESHOOTING

Some of the users may encounter an installation-related issue due to a lack of d3heatmap R package. If so, please use the following commands:

  • install.packages("devtools")
  • devtools::install_github("rstudio/d3heatmap")
  • followed by launching EvaluateCutpoints app, as shown in the User Guide.
