Epigenome-wide association study of pregnancy exposure to green space and placental DNA methylation

############################################################################################################### # Epigenome-wide association study of pregnancy exposure to green space and placental DNA methylation ############################################################################################################### #NOTE: In this study the regression coefficients are reported as the difference in DNA methylation by IQR of continuous green space exposures to green space (NDVI 100m, NDVI 300m, NDVI 500, Distance GS and Use GS) or by exposure group of the categorical variables (Visual GS) (ie. visual access to greenery equal to or more than half of the living room window vs. less than half).
