Fig. 3From: Transient receptor potential ankyrin 1 promoter methylation and peripheral pain sensitivity in Crohn’s diseaseAssociation between CpG − 628 methylation rate and the variable mechanical pain threshold in Crohn patients. In female patients, MPT is lower with higher methylation rates. In male patients, it is inappreciably higher (linear regression; males R2 = 0.006, females R2 = 0.122)Back to article page
