#' Deep Vein Thrombosis Study
#'
#' A data frame containing time to recurrence of thrombosis and several potential
#' prognostic factors measured at baseline for 929 individuals with deep vein
#' thrombosis or unprovoked pulmonary embolism. 147 events of recurrence were
#' observed during a median follow-up time of 37.8 months.

#'
#' @format  The data frame contains observations of 929 individuals and the
#'     following variables:

#'      \item{status}{ = 1 recurrence of thrombosis. }
#'      \item{sex}{ gender. }
