Around 20% to 25% of individuals with rapidly declining FEV1/FVC trajectories experienced wheezing and usual phlegm/bronchitis as adolescents/young adults, according to results published in The ...

For white patients, 15.0% had either their FEV 1 or FVC recategorized from abnormal under the race-adjusted equations to normal using the race-neutral equation. Their FEV 1 decline was similar to ...

Defined by reductions in FEV 1 and FVC and a normal TLC, the nonspecific pattern has classically been considered a marker of early airway disease. The idea is that early, ...

It is standard practice to interpret results from spirometry using race-specific norms, which leads to a decrease in the predicted lower limit of "normal" for FEV 1 and FVC for Black patients. FEV ...

Additionally, doubling of dp-ucMGP increased the risk for FEV 1 and FVC below lower limit of normal (FEV 1, adjusted OR = 2.41; 95% CI, 1.65-3.52; FVC, aOR = 2.48; 95% CI, 1.46-4.22) in the model ...

There is significant disparity in the ratios for postbronchodilator FEV1/FEV6 and FEV1/FVC %, and this disparity is very pronounced in women.

FEV1 helps measure the progression of lung conditions such as chronic obstructive pulmonary disease (COPD) or asthma. FEV stands for forced expiratory volume, which is the air you exhale in one ...

Clinicians should rely on both a low forced expiratory volume in 1 second (FEV 1)/forced vital capacity (FVC) (according to fixed ratio and/or lower limit of normal [LLN]) and a low FEV 1 to avoid ...

The race neutral equations reclassified FEV 1 or FVC from normal to abnormal for 19.2% of Black persons in a large single center cohort study.
