Scatter plots showing the inverse relationship between emphysema and plasma sRAGE by rs2070600 genotype showing that the slopes are not different (genotype × percent emphysema interaction) even if the intercept is lower for subjects carrying the minor allele. COPDGene subjects with sRAGE measured using a LCMS ( n= 491); b QBR (n = 1166); c RBM (n = 569); d SOMAscan (n = 998). The minor allele homozygotes are not shown because of small numbers
