Mean±SD for the test sets of 10 experimental runs are shown. In these experiments, data from the initial 477 patients were used for training (80%), validation (10%) and test (10%) sets. For each run, the model randomly selected one test per patient. Biometric- variables are sex, age, height. Spirometry metrics included are FVC, FEV₁, FEF_25–75 and plethysmography metrics are RV and TLC. Undefined F1 score indicates that either precision, recall or both for that particular class was equal to zero for at least 1 of the 10 experimental runs.
FEF, forced mid-expiratory flow; FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity; RV, residual volume; TLC, total lung capacity.
