In both studies a correlation between the rs1051730 A-allele and lung diffusing capacity (DlCO) and diffusing capacity per unit alveolar volume (Kco) was observed. Consistently, the rs1051730 A-allele conferred increased risk for emphysema as assessed by CT (P = 0.0097 and P = 0.019), with a pooled OR of 1.39 (CI = 1.15\u20131.68; P = 0.00051). Visual emphysema scores and scores based on densities quantified on CT were more pronounced in A-allele carriers, indicating that rs1051730 correlates with the severity of emphysema.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The 15q24\/25 locus in nAChR is associated with the presence and severity of emphysema.
