Figure 1 VEGF and VEGF-D concentrations in the serum of nonsmokers and smokers. Error bars represent standard errors of the mean. Although not statistically significant by univariate analysis, VEGF concentrations were higher in smokers compared with nonsmokers (350 ± 38 ng/mL vs 287 ± 40 ng/mL, P = .26), as were VEGF-D concentrations (622 ± 53 ng/mL vs 556 ± 56 ng/mL, respectively, P = .40). □, Nonsmokers; ■, smokers.
