The associations between weight-related anthropometrics during childhood and lung function in late childhood: a retrospective cohort study

Table 3 Comparisons of different lung function variables at 12.8 years for the study cohort of children without and with asthma who were delivered at Stavanger University Hospital in Norway in 1993–1995

Lung function measure	All n = 453^a	No asthma n = 409	Current asthma n = 37	T-test p-value
	Mean (SD)	Mean (SD)	Mean (SD)
FVC %	100.1 (11.6)	100.2 (11.8)	101.1 (9.5)	0.658
FEV1%	97.5 (10.7)	97.6 (10.8)	96.2 (10.0)	0.456
FEV1/FVC %	97.1 (7.5)	97.2 (7.5)	94.9 (7.6)	0.069
FEF_25–75% /FVC	93.0 (23.5)	93.7 (23.7)	83.5 (20.8)	0.012

Abbreviations: SD standard deviation, FVC % forced vital capacity in percent of predicted, FEV1% forced expiratory volume in first second in percent of predicted, FEV1/FVC % ratio of FEV1 over FVC in percent of predicted, FEF_25–75%/FVC ratio of forced expiratory flow between 25% and 75% of the forced vital capacity over FVC given as a percentage value
