a-b Adpl level (a) and HMW form proportion (b) in men and women COPD patients. Adpl 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 boxplots (5th and 95th percentiles). * p < 0.05; Rank-Sum test. c-d Correlation between Adpl level (vertical), or HMW form proportion (horizontal) and lung function parameters in men (a) and women (b) COPD patients. Pearson correlation coefficients (R) between every parameter and either Adpl level or HMW form proportion were calculated and reported as a point on the graph. The box in the graph represents the critical value for Pearson correlation coefficient to obtain a p < 0.05. Therefore, every point outside the box corresponds to a significant correlation. e Representative blots of Ad form proportion in men and women, determined by using non-denaturant PAGE-SDS followed by a Western blot. HMW forms correspond to the higher molecular weight bands. Admer/total Ad ratios were obtained after densitometric analysis
