What is the impact of over-reading quality review on spirometry in clinical trials?

It has become best practice to review the quality of spirometry data, testing feedback, and overall quality of clinical trials spirometry data.  A study by Mottram et al. identified that an average of 12.2% of test sessions had a change to the original decision by the testing site related to manoeuvre acceptability. This result was calculated from the prevalence of changes made to a spirometry test session by over-readers (OR) in three asthma clinical trials. The data was analysed to determine the number of test sessions where a manoeuvre was either accepted or rejected by the OR, and highlights the importance of quality control for spirometry data.
