Fig. 4From: Genome-wide DNA methylation analysis of pulmonary function in middle and old-aged Chinese monozygotic twinsDifferential methylation patterns for FEV1/FVC from the 12 DMRs. Except the four DMRs (A, I, J, L), one DMRs (K) was positively and seven DMRs (B, C, D, E, F, G, H) negatively associated with FEV1/FVC ratioBack to article page
