Flow chart of statistical analyses and the number of CpGs after each analysis. Note: 1) *Number of significant CpGs were mentioned in an order for FVC, FEV1, and FEV1/ FVC changes respectively. 2) **At age 10 years, for males, between FVC and FEV1, and between FEV1 and FEV1/ FVC, 8 and 3 CpGs are overlapped, respectively; for females, between FVC and FEV1, 21 CpGs are overlapped in the screening. 3) At age 18 years, for males, between FVC and FEV1, and between FEV1 and FEV1 / FVC, 8 and 1 CpGs are overlapped, respectively; for females, between FVC and FEV1, between FEV1 and FEV1/ FVC, and between FVC and FEV1/ FVC, 9, 1, and 2 CpGs are overlapped, respectively, in the screening
