Top metabolites associated with COPD and/or FEV1/FVC. Colors represent standardized effect estimates of the metabolite association with corresponding trait (COPD, FEV1/FVC). Red color means that the trait is associated with a higher metabolite concentration, while blue represents a lower metabolite concetration. For replicated metabolites, replication P-value is shown with stars: *P < 0.05 and ***P < 0.001. HDL – high-density lipoprotein
