Overview
This web app presents a data-driven approach to predict heart
transplantation survival probabilities over time. The prediction is soley based on
medical information that is available at transplant time, as explained in detail in our
Scientific Reports manuscript. The app presents two modules for performing the analysis:
(1) Manual Entry, where users can insert the values of predictor variables using several text boxes.
(2) CSV Entry, where users can upload the values of predictor variables using a comma seperated variable (CSV) file.
These modules can be accessed using the tabs on the side bar to the left.
In addition, one can find more informations about our source code and research teams using the last two tabs at the left.
How to Use the App?
We have created a voice-over-screen video to demonstrate how the app can be used to achieve
correct results (and no errors). We highly advise the reader to view the video prior to his/her's
first use; the video is short and will reduce the start-up time for new users.
