From: NOX4 expression and distal arteriolar remodeling correlate with pulmonary hypertension in COPD
Correlations of the abundance of NOX4 protein in pulmonary distal arteries with the volume of distal pulmonary arteries and pulmonary functions. a The correlation between the abundance of NOX4 protein in pulmonary distal arteries and FEV1/FVC (r- = 0.411,P < 0.05); (b) The correlation between the abundance of NOX4 protein in pulmonary distal arteries and FEV1%pred (r = − 0.407,P < 0.05); (c) The correlation between the abundance of NOX4 protein in pulmonary distal arteries and WA% (r = 0.53,P < 0.01); (d) The correlation between the abundance of NOX4 protein in pulmonary distal arteries and WT% (r = 0.79,P < 0.01). FEV1/FVC: forced expiratory volume in one second/ forced vital capacity; FEV1%pred: forced expiratory volume in one second total predicted value; WA%: the pulmonary artery smooth muscle area accounted for the percentage of total vascular area; WT%: the pulmonary artery smooth muscle thickness accounted for the percentage of vascular diameter
