Quality of spirometry.
I can not precisely say if these were first or next spirometry in uor patients. My impression is that in the majority there were first spirometry, as they were performed in 6 months period of time in majority in hospitalized patients. When I revied the tests assessing quality these were usually the first tests at least in our lab. If the patient had more tests than one, the first test was included in analysis. The expeption was failed test that was shorty repeated with success. Usually there were not real problems with duration of forced expiration. As I remember FET in patients with good test was over 8 s., and in patients with at least 1 good trial over 7 s. Stefan Wesolowski

The high number of patients fullfilling ATA criteria is astonishing. I wonder if the patients performed the spirometry for their first time in life or - as patients - were already used to perform the test? Could you stratify for that? Did you really apply the hard criteria of the ATS, i.e., exhalation larger than 6 s and smaller than 15 s and did 75% of the patient reach a plateau with minimal variation in flow rate in the last second? I appreciate your reply (schulz@helmholtz-muenchen.de). Thanks a lot. Holger
