#' Aortic Stenosis RCT data
#'
#' Data from 5 randomized controlled trials of transcatheter aortic valve
#' replacement vs surgery in patients with Aortic Stenosis. The outcome is time
#' until death from any cause. For each RCT, 
#' we reconstructed the individual patient data for each randomization group.
#' We first extracted the time and survival probability coordinates 
#' from the Kaplan-Meier curves using the 
#' DigitizeIt software (\url{http://www.digitizeit.de/}). We used 
#' these coordinates, the total numbers of events, and the 
#' numbers of participants at risk to determine individual
#' event times and event indicators. (Guyot, BMC Med Res Method 2012)
