Figure 4From: Modulation of glutaredoxin in the lung and sputum of cigarette smokers and chronic obstructive pulmonary diseaseCorrelation of tissue Grx1 with lung function parameters. Correlations between the percentage of Grx1 positive macrophages (of total macrophage population examined) and lung function parameters. The percentage of Grx1 positive macrophages was observed to significantly correlate with FEV1 (r = 0.45, p = 0.008), FEV1% (r = 0.46, p = 0.007) and FEV/FVC% (r = 0.55, p = 0.001).Back to article page
