HR and 95%CI for B2 (A), M (B), G2 (C) and VB (D) stratified by cereal fibre intakes. Data are HR with 95% confidence intervals. Cox proportional hazard regression models were used, adjusted for parental education level, mother’s age at menarche, energy intake at baseline and percent body fat at baseline, with the group of those in the lowest tertile of both total soy and dietary cereal fibre intakes serving as the reference group. p for interactions refers to the 2-way interactions of cereal fibre intakes on the relations between dietary soy intake and puberty markers. A, B Ngirl=2152. Range of soybean intakes: 1st tertile (0–8.2), 2nd tertile (8.5–39.6) and 3rd tertile (40.1–69.0). Participants in groups: low soy, low cereal fibre: n=285; low soy, medium cereal fibre: n=217; low soy, high cereal fibre: n=222; medium soy, low cereal fibre: n=265; medium soy, medium cereal fibre: n=223; medium soy, high cereal fibre: n=220; high soy, low cereal fibre: n=309; high soy, medium cereal fibre: n=221; high soy, high cereal fibre: n=192. C, D Nboy=2629. Range of soybean intakes: 1st tertile (0–3.2), 2nd tertile (4.6–48 2) and 3rd tertile (49.1–82.6). Participants in groups: low soy, low cereal fibre: n=350; low soy, medium cereal fibre: n=266; low soy, high cereal fibre: n=269; medium soy, low cereal fibre: n=320; medium soy, medium cereal fibre: n=272; medium soy, high cereal fibre: n=268; high soy, low cereal fibre: n=376; high soy, medium cereal fibre: n=274; high soy, high cereal fibre: n=234
