- Study compares oscillometry and spirometry in diagnosing COPD or asthma in Chinese patients.
- Oscillometry showed moderate consistency with spirometry pre-bronchodilator (kappa = 0.4188).
- Post-bronchodilator results in COPD group showed moderate consistency (kappa = 0.4662).
- Oscillometry required fewer attempts than spirometry (8.5 vs. 11.0, p < 0.0001).
- High positive predictive value (87.4%) suggests oscillometry could rule-in COPD when spirometry is not feasible.
