#' Propensity score matched elective laparoscopic cholecystectomies from NSQIP Registry
#'
#' A dataset containing 48,240 records of elective laparoscopic cholecystectomies from the NSQIP registry.
#' This data was derived from a larger dataset, `nsqipBileSpill::df`, by propensity score matching for assignment
#' to the variable `spill` against various pre-operative risk factors.
