From: Increased levels of (class switched) memory B cells in peripheral blood of current smokers
B cells in peripheral blood. A) Percentages of total B cells in peripheral blood of COPD patients (closed symbols) and healthy individuals (open symbols). The result of the multiple linear regression analysis (i.e. corrected for current smoking) is depicted in the figure. B) The same results are depicted, but divided in subgroups based on the presence of COPD and the current smoking status. In this figure the results of the Mann Whitney U tests are depicted. * indicates that p < 0.05
