#' @description
#' Meta-analysis of studies of the diagnostic test accuracy of
#' fractional exhaled nitric oxide (FENO) for diagnosis of asthma.
#' 
#' The data were collected for a systematic review by Karrasch et
#' al. (2017) and are published as a supplement (Appendix 1) to
#' Schneider et al. (2017). They have been preprocessed for use in R
#' package \bold{diagmeta}.
