Final linear regression model predicting BMI at 17 years old. Linear regression model for the outcome of BMI at 17-years was formed by backward selection with pre-pregnancy BMI, maternal smoking at 18-weeks gestation and GWG, all pyrosequenced CpGs, cell counts and potential me-QTLs (rs6565624_G, rs3830068_G, rs12452184_A). The model (r² = 0.243 (SE = 0.15), includes independent effects of rs6565624_G, MSI2 CpG1, RAPH1, maternal smoking at 18-weeks, pre-pregnancy BMI, CD8+, CD4 + T cells, and granulocytes.
