(A) Mean values and standard deviation of plasma VEGF-A levels (pg/mL) did not significantly differ between the study groups. (B) Mean values and standard deviation of plasma TGF-beta1 were significantly greater in both LC-COPD and LC-only patients compared to non-LC control subjects. Statistical Significance: ** p < 0.01, *** p < 0.001 between any group of LC patients and the non-LC control subjects. The absence of statistical symbols indicates that no significant differences were encountered between groups for the different study comparisons.
