Schneider2017: Meta-analysis of studies of the diagnostic test accuracy of FENO for diagnosis of asthma

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 diagmeta.

Format

A data frame with the following columns:

study_id	numeric study ID
author	first author
year	year of publication
group	information on subgroup
cutpoint	cutpoint (FeNO [ppb])
tpos	number of true positives
fneg	number of false negatives
fpos	number of false positives
tneg	number of true negatives

Examples

# FENO dataset

data(Schneider2017)

diag1 <- diagmeta(tpos, fpos, tneg, fneg, cutpoint,
                  studlab = paste(author, year, group),
                  data = Schneider2017,
                  log.cutoff = TRUE)
