Establishing age specific spirometry reference ranges for children/adolescents of Karachi, Pakistan: Randomized trials
-In boys, but not girls, higher fat mass was associated with lower levels and lung growth rates of FEV1 and FEF25-75.
How childhood body composition determines lung health in adults
Robust linear regression models adjusted for sex, age, height, BMI, sex*age interaction, sex*height interaction, current smoking, and pack-years were used to analyze the cross-sectional association between air pollution exposure and lung function levels, as measured by: [FEV.sub.1], FVC, [FEV.sub.1]/FVC, and FEF25-75. Two-sided p-values <0.05 were considered statistically significant.

Comparison of the sitting-to-standing cycle ergometry versus treadmill approach to graded exercise testing on cardiorespiratory values in overweight people with mild asthma
With regard to the spirometric index FEF25-75, this study revealed a marked difference between patients colonised by PA and those who were not colonised, with a significantly greater rate of change in the former group.
The impact of chronic pseudomonal infection on pulmonary function testing in individuals with cystic fibrosis in Pretoria, South Africa
Mild smokers showed a 5.39% decrease in FEF25-75 whereas a 01% increase in FEV1 / FVC ratio compared to non-smokers.
EFFECT OF SMOKING ON RESPIRATORY PRESSURES AND LUNG VOLUMES IN YOUNG ADULTS
Both adults and children demonstrate obesity related reductions in FEF25-75 compared to lean subjects [58]; reduced FEF25-75/FVC has been regarded as marker of increased hyperresponsiveness [136].
Obesity and asthma: physiological perspective
The exact parameters included in the test can vary somewhat from instrument to instrument; but three parameters, FVC, FEV1, and FVC/FEV1, are universal, and two others, FEF25-75 and maximum flow, are included in most cases.
Case report: COPD and anxiety resolved by integrative medicine
Eric Jaeger Master Lab pulmonary function equipment was used to measure the forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory flow 25-75% (FEF25-75), total lung capacity (TLC), residual volume (RV) and diffusion capacity for carbon monoxide (DLCO).
