Fig. 1From: Osteoarthritis genetic risk acting on the galactosyltransferase gene COLGALT2 has opposing functional effects in articulating joint tissuesMethylation quantitative trait locus (mQTL) analysis. Violin plots show the DNA methylation values at synovium samples (nā=ā49ā79 patients; differences in numbers due to a variable number of patient samples per CpG passing quality control) for A cg18131582 (CpG9) and its 11 flanking CpGs stratified by genotype at rs11583641 and for B cg15204595 and cg21606956 stratified by genotype at rs1046934. Solid and dashed horizontal lines represent the median and interquartile range. P values were calculated by linear regression. Significant P values (Pā<ā0.05) are marked: **Pā<ā0.01; ***Pā<ā0.001; ****Pā<ā0.0001Back to article page
