Table 2 Correlation between lung function parameters and Ad_pl level or HMW form proportion in non-hypoxemic and hypoxemic COPD patients. Ad_pl level was measured by ELISA and HMW form proportion was determined using a non-denaturing PAGE-SDS followed by a Western blot. Data were represented as Pearson correlation coefficient _(p value)
