Performance comparisons of the DMLP model, pulmonologists and ATS/ERS decision tree
| Accuracy (%) | P value (compared with DMLP model) | |
| DMLP model | 94.67±2.63 | – |
| Pulmonologists | 66.67±14.63 | 0.0051 |
| ATS/ERS decision tree | 75.61 | <0.0001 |
Accuracies (mean±SD) of the DMLP model (n=10), pulmonologists (n=6) and the ATS/ERS decision tree for classifying 82 spirometry tests as normal, obstructive, restrictive and mixed obstructive-restrictive disease tests when compared with the ‘true’ labels based on the ATS/ERS interpretations using full PFTs with spirometry and plethysmography. Comparison of the groups were conducted using two-sample t-tests. The lowest accuracy was found in the pulmonologists and the highest in the DMLP. No differences were observed in the accuracies of the pulmonologists and the ATS/ERS decision trees (p=0.5958).
