From their forced vital capacity, home cleaners lost an extra 4.3 milliliters a year and occupational cleaners lost an additional 7.1 milliliters a year.
For each of the participant, vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), forced vital capacity ratio (FEV1/FVC) and forced expiratory flow FEF (25%-75%) were measured.

The primary endpoint is the effect of neoGAA on respiratory muscle strength as measured by percent predicted forced vital capacity in the upright position.
Recorded respiratory parameter were forced vital capacity (FVC), forced expiratory volume at one second (FEV1), and peak expiratory flow rate (PEFR).
Changes in asthma scores, lung function parameters (forced expiratory volume in 1 s [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, maximum mid-expiratory flow rate) and the concentrations of IL-4 and IL-6 in EBC were measured.
Forced vital capacity (FVC), forced expiratory volume in 1 second ([FEV.sub.1]), [FEV.sub.1]/FVC, forced expiratory flow (FEF25-75), FEF25, FEF50, FEF75 and peak expiratory flow were measured using forced expiratory values.
Several types of measurement are taken--for example, forced vital capacity (FVC) is the total amount of air that can forcibly be blown out after inhalation, while forced expiratory volume in 1 second (FEV1) is the amount of air that can be blown out in one second.
Researchers calculated a 95 percent confidence limit around the slopes of decline of ALSFRSr scores, forced vital capacity (FVC) and grip strength of the ProAct historical database subjects, and evaluated if trial subjects fell within or outside those limits.
