The Global Lung Function Initiative 2012 Equations Are as Well-Suited as Local Population Derived Equations to a Sample of Healthy Professional Firefighters

Table 1

Measured and predicted lung function values using Gore and GLI equations. Participants are never-smokers with no history of doctor-confirmed asthma or lung disease. Values are means (standard deviation) (N = 212).

		Predicted		LLN
		Gore	GLI	Gore	GLI
FEV1 (L)	4.52 (0.67)	4.22 (0.42)	4.20	2.95 (0.42)	3.29
FVC (L)	6.05 (0.82)	5.35 (0.61)	5.30	3.81 (0.61)	4.14
FEV1/FVC ratio	0.75 (0.06)	0.80 (0.02)	0.80 (0.02)	0.71 (0.02)	0.69

SAMFS = South Australian Metropolitan Fire Service; LLN = lower limit of normal; FEV₁ = forced expiratory volume in 1 second; FVC = forced vital capacity; FEV₁/FVC ratio = forced expiratory volume in 1 second to forced vital capacity ratio. bronchodilator values. significant difference between Gore and GLI with Student’s -test ().
