Number of respondents with COPD previously diagnosed and diagnosed by spirometry during the study

	Ukraine (n = 939)	Kazakhstan (n = 945)	Azerbaijan (n = 933)
Previously diagnosed COPD	N = 10 (1.0%)	N = 13 (1.4%)	N = 4 (0.4%)
Diagnosed by spirometry	N = 30 (3.2%)	N = 63 (6.7%)	N = 35 (3.8%)
Firstly diagnosed by spirometry	N = 27 (2.9%)	N = 58 (6.1%)	N = 33 (3.5%)
COPD severity by GOLD stagea:
I (Mild)	13 (1.4%)	26 (2.8%)	13 (1.4%)
II (Moderate)	17 (1.8%)	37 (3.9%)	22 (2.4%)

GOLD Stage I (Mild): FEV₁/FVC < 0.70 and FEV1 ≥ 80% predicted

GOLD Stage II (Moderate): FEV₁/FVC < 0.70 and 50% ≤ FEV₁ < 80% predicted

^aThere were no respondents diagnosed with COPD III or IV GOLD stages
