- Compressed (mouth) and uncompressed (thoracic measurement) flow values (mean, SD and range) at different levels of forced expiration; at peak expiratory flow (PEF), maximal expiratory flow when 75% of forced vital capacity remains exhaled (MEF75), MEF 50 and MEF 25. Means (M) and ranges (RD) of the differences and the p-values of the paired t-test results between thoracic and mouth measurements in each group are presented.
