near-marginal significancep = 0.188
When splitting controls and COPD patients into two subgroups - less than and above 60 years of age, we found near-marginal significance for shorter telomeres in COPD patients above 60 years compared to controls in the same subgroup (17558.73 ± 1536.78 (SEM) bp vs. 22257.88 ± 3684.15 (SEM) bp., p = 0.188, Fig. 2 ), but no difference was seen in younger subgroups ( p = 0.479).
