Abstract

In the originally published article, errors were identified in Tables 1, 2, 3 and 4, and 5. The correct tables are presented as follows: Summary of spirometry results of the patients. % Pred FVC= predicted percentage of function vital capacity, % Pred FEV1 = predicted percentage of forced expiratory volume in 1 s, % Pred FEV1/FVC= predicted percentage of FEV1/FVC, SD= standard Deviation, IQR= inter quartile range % Pred FVC % Pred FEV1 FEV1/FVC % Pred FEV1/FVC Median 85.0 67.0 68.6 82.5 Mean 84.1 66.9 64.5 78.6 SD 15.8 22.6 18.1 22.2 IQR 19.0 35.5 29.3 37.2 Summary of polysomnography results of the patients. AHI: Apnea-Hypopnea Index, SpO2: mean oxygen saturation T90%: time spent below 90% oxygen saturation, LSO2: lowest oxygen saturation, SD= standard Deviation, IQR= inter quartile range AHI SpO2 T90% LSO2 Median 38.9 93.0 3.0 80 Mean 43.6 92.4 12.3 75.5 SD 28.3 4.2 18.6 11.4 IQR 48.9 2.0 15.0 9.0 Relation between polysomnography features and gender. AHI: Apnea-Hypopnea Index, SpO2: mean oxygen saturation T90%: time spent below 90% oxygen saturation, LSO2: lowest oxygen saturation, SD= standard Deviation, IQR= inter quartile range AHI SpO2 T90% LSO2 Female Male Female Male Female Male Female Male Median 16.9 47.3 95 93 0.3 6 81.5 79 Mean 25.1 51.0 94.3 92 4.2 15.5 81.2 73.4 SD 21.0 27.6 1.7 4.6 10.6 20.1 5.1 12.4 IQR 27.0 46.3 0.012 3.0 1.3 21 5.7 13.5 P value (Mann-Whitney) < 0.001 < 0.001 < 0.001 0.002 Relation between spirometry features and gender.
