MAPK1 and asthma: Table 5 presents the association of the MAPK1 5’CGI methylation status with asthma. For the logistic regression analysis, we dichotomized the methylation into higher and lower groups. MAPK1 methylation status was dichotomized into higher methylated and lower methylated groups with cut off continous variable of median of promoter methylation percentage (50%) while performing the analysis. Lower methylation of the MAPK1 5’CGIs was found to be positively associated with asthma compared to higher methylation of MAPK1 5’CGIs (adjusted OR = 2.33, 95% CI = 1.01–5.39, p = 0.020).
