Abstract
It9s recommended that spirometric testing in children be completed while sitting, our experience is that children feel more comfortable standing during spirometry. <b>Aim:</b> We sought to compare spirometric results obtained from the sitting (SI) and standing (ST) positions. <b>Method:</b> Two testing sessions were performed in random order (SI vs ST position: testing 30-45 min. apart) in 118 children aged 7-13 y-rs, attending randomly selected, primary school in town of Katowice (response rate: 92%). <b>Results:</b> Tests of acceptable quality were found in 77.9% of ST and 77.1% of SI position - 29 girls and 49 boys (mean age=9.0±1.6 y-rs). The frequency of chronic cough was 33.7%, of chest wheeze was 11.6%, and of attacks of dyspnea was 9.0%. Higher values of spirometric variables on ST, compared to SI position, were for FVC (2.12±0.41 l vs 2.11±0.39 l) and FEV<sub>1</sub> (1.78±0.36 l vs 1.77±0.35) but the differences were not statistically significant. Mean relative between-position differences [RBPD] were for FVC: 5.5±4.5%, FEV<sub>1</sub>: 5.8±6.6%, PEF: 12.4±9.5%, and FEF<sub>2575</sub>: 15.9±16.8%. RBPD ≤ 5% was found in: FVC: 56.4 %, FEV<sub>1</sub>: 69.2 %, PEF: 21.7%, and FEF<sub>2575</sub>: 24.3%. Patterns for FEF<sub>25</sub>, FEF<sub>50</sub>, and FEF<sub>75</sub> were similar. RBPD were related to age in the case of FEV<sub>1</sub> (p=0.005), FEF<sub>25</sub> (p=0.02), FEF<sub>2575</sub> (p=0.01) where older children had smaller RBPD. FVC RBPD was lower (p=0.01) in subjects with current wheeze while PEF RBPD was lower (p=0.02) in children with asthma. No cases of adverse events. <b>Conclusion:</b> In epidemiological studies of children, the position of spirometric testing does not seem to affect the result of lung function assessment or the safety level of the measuring procedure.

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
