For each practice characteristic we report the mean and standard deviation of the "spirometry proportion".
*The "spirometry proportion" is defined as the proportion of adult patients within the practice receiving first-time prescriptions for medication targeting obstructive lung disease who had spirometry performed in the 18-month interval.
For each practice we calculated a "spirometry proportion" defined as the proportion of adult patients within the practice receiving first-time prescriptions for medication targeting obstructive lung disease who had spirometry performed in the 18-month interval.
The distribution of the "spirometry proportion" among general practice is illustrated in Figure 1 and it demonstrates quite a large variation between practices.
42 This means spirometry to detect airflow limitation, or computed tomography to detect emphysema, is required to recognize chronic smokers with COPD.
RESULTS: The mean unadjusted proportion of adherent patients in clinics was 0.715 (interdecile range 0.559-0.826).
In each study the overall mean jitter, the proportion of fibers with normal neuromuscular transmission, and the proportion of fibers showing blocking were determined.
The overall mean proportion of IE patients that developed stroke was 0.158 ± 0.091, and the mean proportion of patients that underwent valve surgery was 0.324 ± 0.188.
The mean proportion of AA in mixed race groups was 56%.
