Figure 4 Correlations of SIRT1 expression, IL-6 and IL-8 with FEV1 and FEV1/FVC in AECOPD patients. (A) Correlation between SIRT1 expression and FEV1 in the serum of AECOPD patients. A significant linear positive correlation was observed between SIRT1 activity and FEV1 in AECOPD patients (r2=0.75, P<0.001). (B) Correlation between SIRT1 expression and FEV1/FVC in the serum of AECOPD patients. A marked linear positive correlation was found between SIRT1 activity and FEV1/FVC in AECOPD patients (r2=0.74, P<0.001). (C) Relation between IL-6 and FEV1 in AECOPD patients. IL-6 had a remarkable linear negative relation with FEV1 in AECOPD patients (r2=0.83, P<0.001). (D) Relation between IL-6 and FEV1/FVC in AECOPD patients. IL-6 had a notable linear negative relation with FEV1/FVC in AECOPD patients (r2=0.81, P<0.001). (E) Association between IL-8 and FEV1 in AECOPD patients. There was an obvious linear negative association between IL-8 and FEV1 in AECOPD patients (r2=0.86, P<0.001). (F) Association between IL-8 and FEV1/FVC in AECOPD patients. There was an evident linear negative association between IL-8 and FEV1/FVC in AECOPD patients (r2=0.80, P<0.001).
