Introduction

dsSurvival is a package for building survival functions for DataSHIELD (a platform for federated analysis of private data). These are server side functions for survival models, Cox proportional hazards models and Cox regression models.

A tutorial in bookdown format with executable code is available here:

https://neelsoumya.github.io/dsSurvivalbookdown/

DataSHIELD is a platform in R for federated analysis of private data. DataSHIELD has a client-server architecture and this package has a client side and server side component.

If you use the code, please cite the following manuscript:

Quick start

and R Studio

https://www.rstudio.com/products/rstudio/download/preview/

  • Install the following packages in R:
install.packages('devtools')
library(devtools)
devtools::install_github('neelsoumya/dsSurvivalClient')
devtools::install_github('datashield/[email protected]')
install.packages('rmarkdown')
install.packages('knitr')
install.packages('tinytex')
install.packages('metafor')
install.packages('DSOpal')
install.packages('DSI')
install.packages('opalr')
  • Follow the tutorial in bookdown format with executable code and synthetic data:

https://neelsoumya.github.io/dsSurvivalbookdown/

This uses the Opal demo server which has all server-side packages preinstalled

https://opal-sandbox.mrc-epid.cam.ac.uk/

You can also see the script simple_script.R

https://github.com/neelsoumya/dsSurvival/blob/main/vignettes/simple_script.R

Installation

In the newer version of Opal your window may look like the screenshot below

See the link below on how to install a package in Opal

https://opaldoc.obiba.org/en/latest/web-user-guide/administration/datashield.html#add-package

If you have an older version of Opal, please use this version by Stuart Wheater

https://github.com/StuartWheater/dsSurvival

install.packages('devtools')

library(devtools)

devtools::install_github('neelsoumya/dsBaseClient')

devtools::install_github('neelsoumya/dsSurvivalClient')

If you want to use a certain release then you can do the following

library(devtools)

devtools::install_github('neelsoumya/[email protected]')

If you want to try privacy preserving survival curves (available in v2.0), you can use the main branch or you can do the following

library(devtools)

devtools::install_github('neelsoumya/dsSurvivalClient', ref = 'privacy_survival_curves')

or

library(devtools)

devtools::install_github('neelsoumya/[email protected]')

Usage

A tutorial with executable code in bookdown format is available here:

https://neelsoumya.github.io/dsSurvivalbookdown/

A screenshot of the meta-analyzed hazard ratios from a survival model is shown below.

For polished publication ready plots, use the following script forestplot_FINAL.R

https://github.com/neelsoumya/dsSurvival/blob/main/forestplot_FINAL.R

If you want to plot survival curves or Kaplan-Meier curves, see the following link:

Release notes

v1.0.0: A basic first release of survival models in DataSHIELD. This release has Cox proportional hazards models, summaries of models, diagnostics and the ability to meta-analyze hazard ratios. There is also capability to generate forest plots of meta-analyzed hazard ratios. This release supports study-level meta-analysis (SLMA).

A shiny graphical user interface for building survival models in DataSHIELD has also been created by Xavier Escriba Montagut and Juan Gonzalez. It uses dsSurvival and dsSurvivalClient.

v1.0.1: Minor fixes.

v2.0.0: This has privacy preserving survival curves.

v2.1.0: This has vcov() functionality.

v2.1.1: This has minor fixes.

v2.1.2: This has minor fixes.
