The LLN of FEV[sub]1/FVC and maximal midexpiratory flow (MMEF
, equals to FEF[sub]25-75%) computed using the 2012-GLI equations and 2006-Hong Kong equations was both lower than the present version.
Pulmonary parameters such as TV, VC, FVC, [FEV.sub.1], MMEF
, PEFR, and MVV were significantly reduced in cases than controls and inversely correlated with the Cobb's angle.
However, the increase in [FEV.sub.1], MMEF
and [MEF.sub.50] due to both doses of boiled extract and increase in [MEF.sub.75] and [MEF.sub.25] due to its lower doses were significantly lower than those of theophylline (p < 0.05 to p < 0.001).
"FEV1 is a measure of large airways, FVC of total lung volume and MMEF
of smaller airways, so they measure slightly different things and we wouldn't necessarily expect to see all outcomes behaving the same," said Dr.
Lung function parameters measured were: FEV[sub]1, peak expiratory flow (PEF), forced expiratory flow at 50% of forced vital capacity (FEF[sub]50), forced expiratory flow at 75% of forced vital capacity (FEF[sub]75), and maximum mid-expiratory flow rate (MMEF
To correlate 6MWT, FEV1 and MMEF
75-25 among each other and establish the individual significance in evaluating bariatric subjects.

Pulmonary function measures analyzed were forced vital capacity (FVC), forced expiratory volume at 1 sec (FE[V.sub.1]), peak expiratory flow (PEF), and maximum mid-expiratory flow (MMEF
The mean MMEF
at rest in swimmers was 4.25 [+ or -] 0.80 litres/sec
The highest levels for forced vital capacity (FVC), forced expiratory volume in one second (FEV1), maximal midexpiratory flow (MMEF
), peak expiratory flow (PEF), and maximal expiratory flow at 75%, 50%, and 25% of the FVC (MEF75, MEF50, and MEF25 respectively) were taken independently from the three curves.
Compared to students living in the least polluted communities, children living in the most polluted communities have shown a reduction in two measures of lung function: a cumulative 3.4% reduction in [FEV.sub.1] (forced expiratory volume) and a 5.0% reduction in MMEF
(maximal mid-expiratory flow).

at rest in swimmers was 4.25+0.80 liters/sec and in controls was 4.19+1.02 liters/sec.
