Reproducibility of the EasyOne spirometer in the clinical setting with spirometry naive participants

	Coefficient of variation (95% confidence intervals)	95% limits of agreement (1.96* SDi)
FVC*	3.3% (2.1 – 4.5)	0.24 L
FEV1†	2.6% (1.8 – 3.3)	0.18 L
FEV1/FVC	1.9% (0.9 – 3.0)	0.05
FEV6‡	2.8% (1.7 – 3.8)	0.23 L
FEF25–75§	6.8% (3.1 – 10.4)	0.45 L
PEF∥	5.1% (3.1 – 7.1)	1.05 L/sec

^*FVC = forced vital capacity

^†FEV₁ = forced expiratory volume in one second

^‡FEV₆ = forced expiratory volume in six seconds

^§FEF_25–75 = forced expiratory flow between 25% and 75% of vital capacity

^∥PEF = peak expiratory flow rate
