Furthermore, data from seven studies demonstrated highly significant positive association between telomere length and spirometric measurements including FEV 1 (β=0.0455, p=1.07×10 −7 with fixed and random effects; I 2 =0%), FVC (β=0.0401, p=2.07×10 −7 with fixed and random effects; I 2 =0%), and FEV 1 /FVC (β=0.0238, p=5.27×10 −7 with fixed and random effects; I 2 =0%) 25 .
