Disease-Specific Comorbidity Clusters in COPD and Accelerated Aging.

As for the parallel (co)morbidity clusters in COPD and controls, telomere length was comparable between both “Less (Co)morbidity” clusters C1 and X1, and significantly reduced in cluster C2 versus X2, while the difference failed to reach statistical significance for cluster C3 versus X3 (10.22 ± 1.90 versus 10.82 ± 1.45 kbp, p = 0.05) ( Figure 5 and Appendix A , Table A2 ). 4.
