Description

R package for analysing composite responder endpoints in rheumatology with up to two continuous and one binary components.

Getting Started

Install from Github using devtools::install_github("martinamcm/augbin_rheum")

Implementation as a Shiny app with further documentation on functionality and examples available at AugBin

Details

Function augbinrheum is used to conduct the analysis with the following arguments:

  • data Data with columns ordered as follows: patient ID, treatment arm, continuous outcome(s), binary outcome followed by the baseline continuous measure(s)
  • cts Number of continuous outcomes in the composite which can be 1 or 2. Defaults to 1.
  • bin Number of binary outcomes in the composite which can be 1 or 0. Defaults to 1.
  • dichot Responder threshold in each of the continuous outcomes. For one continuous outcome input as ‘d1’ and for two continuous outcomes input as ‘c(d1,d2)’
