• HR - hazard ratio at that tipping point

• CONFINT - 95% CI at tipping point

• METHOD - sampling type used

• ARMIMP - arm imputed

• TIPPT - parameter where upper CL first crosses 1

• TIPUNIT - parameter meaning

  reason = "Early dropout",
  impute = "docetaxel",
  imputation_model = "weibull",
  J = 10,
  tipping_range = seq(0.1, 1, by = 0.05),
  cox_fit = cox1,
  verbose = TRUE,
  seed = 12345
