Accurate prediction of subject recruitment for randomized clinical trials (RCT) remains an ongoing challenge. Many previous prediction models rely on parametric assumptions. We present functions for non-parametric RCT recruitment prediction under several scenarios.
You can install the development version of RCTRecruit from GitHub with:
devtools::install_github("imalagaris/RCTRecruit")library(RCTRecruit)
LoadData(gripsYR1, ScreenDt, Enrolled)
#> 
#> Variables Enrolled and ScreenDt were successfully loaded
Time2Nsubjects()
#> Enrolling 50 subjects requires 137 weeks
#> 
#>  2.5%   50% 97.5% 
#>   137   137   137
GetDistance(gripsYR2Weekly$enrolled)
#>  2.5%   50% 97.5% 
#>    85    85    85
