Abstract
UNLABELLED: In N. America, over the past decade, various airway clearance techniques (ACT) have been introduced for the treatment of cystic fibrosis (CF). We hypothesized that autogenic drainage (AD), an ACT developed in Belgium would be as effective as postural drainage with percussion (PD) in treating patients with CF. METHODS: Thirty-six CF patients, aged 12-18 years, with Shwachman score 65-98, were enrolled in a 2-year cross-over trial. Patients were matched as pairs and members of each pair were randomly assigned to two groups. For the first study year, Group A performed PD while Group B performed AD. At the end of 1 year Groups A and B crossed over physiotherapy techniques. Clinical status and pulmonary function (FVC, FEV(1), FEF(25-75)) were measured at 3 monthly intervals. Only results from the first year of the study are reported, as 10 out of 17 patients who had completed performing AD for the first year refused to change back to PD for the second year. RESULTS: During the first year of the study, both the AD and PD groups demonstrated improved pulmonary function with no significant difference between the two groups. Change in FVC and FEV(1) percent predicted for Groups A and B was 0.47 ± 1.65(se) versus 2.35 ± 1.51(se) and 2.09 ± 2.2(se) versus 0.92 ± 2.25(se). However, CF patients exhibited a marked preference for the AD technique. Results suggest that both AD and PD are effective methods of performing physiotherapy for CF patients and that the benefits of either technique are enhanced by measures which encourage adherence.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
