Criteria for assessing the severity of airflow obstruction (based on the percent predicted postbronchodilator FEV1) are as follows: Stage I (mild): FEV1 80% or greater of predicted Stage II (moderate): FEV1 50-79% of predicted Stage III (severe): FEV1 30-49% of predicted Stage IV ...
PB-FEV1 was expressed in percent of predicted value based on the patients’ age, gender, ethnicity, and height. Patients were divided into four groups according to the severity of airflow limitation based on PB-FEV1: < 30% predicted (very severe); 30–49% predicted (severe); 50–79% pre...
On average, lung function of the study participants was normal and only 7% of the study participants had either self-reported COPD, emphysema, or chronic bronchitis [85]. A subsequent analysis of this study revealed that the percent emphysema was inversely related to right ventricular volumes and...
percent radiographic emphysema (Spearman\(\rho\) = −0.167) in 208 COPD subjects in the LGRC cohort (Fig.3E). We then performed immunostaining for NUPR1 and SFTPC and quantified NUPR1 in SFTPC+AT2 cells using CellProfiler, and found AT2 NUPR1 was decreased in COPD lung tissue (Fig....
