Analysis protocol for the project entitled "Determination of the optimum strategy for interpretation of peak expiratory flow in the context of screening for impaired lung function"

This upload contains the analysis protocol for the project "Determination of the optimum strategy for interpretation of peak expiratory flow in the context of screening for impaired lung function", the purpose of which is to determine how peak expiratory flow readings should be interpreted to obtain the highest predictive value for impaired lung function (with spirometry as the gold standard). The paper describing the project is available from Respiratory Medicine and Research, https://doi.org/10.1016/j.resmer.2023.101015 List of files: Analysis_protocol_20220624.pdf: Analysis protocol PEF.zip: ZIP-compressed folder containing all Stata syntax and folder structure for the planned analyses. At the time the files were deposited at Zenodo, the analyses had not yet been conducted. LICENSE.txt: Text file describing the license under which the other files are released. The published paper contains updated versions of the analysis protocol and the Stata syntax files. If you want to reproduce the findings in the paper, or if you want to modify the code for use in your own projects, please use the updated versions of the files
