Baseline lung function by FVS (% predicted) in 80 children hospitalized for wheezing in infancy and attending the follow‐up visit during teenage years

Parameters in FVS (n = 80)	Mean (95% confidence interval)	Median (range)
FVC	97.79	96.98
	(95.04–100.55)	(71.86–137.67)
FEV1	92.23	90.78
	(89.35–95.12)	(62.64–127.62)
FEV1/FVC	94.55	95.22
	(92.67–96.43)	(68.07–109.78)
MEF50	81.43	81.88
	(77.20–85.67)	(36.04–120.95)
MEF25	71.68	74.40
	(71.68–76.27)	(29.64–114.13)

FVC = forced vital capacity; FEV₁= forced expiratory volume in 1 sec; MEF₅₀= maximal expiratory flow at 50% of FVC; MEF₂₅= maximal expiratory flow when 25% of FVC remains to be expired.

FVS = flow‐volume spirometry.
