Relationship between tertile of humeral vBMD as measured at 9.9 years of age and the risk of fracture risk over the following 2 years, adjusted for age, sex, ethnicity, maternal education, paternal social class, height, and log-transformed weight. Graphs show mean ORs ± 95% CIs for the association between each tertile and fracture risk (1 = lowest tertile, 3 = highest), calculated by logistic regression. The highest tertile was taken as the baseline category, and the p values are for the test for trend. Humeral vBMD was reduced to a categorical variable (tertiles) after adjustment. The dotted line represents the null value of 1.

Relationship between tertile of (A) TBLH BMC or (B) TBLH BA as measured at age 9.9 years and the risk of fracture over the following 2 years. TBLH BMC is adjusted for (i) age, sex, ethnicity, maternal education, and paternal social class, and (ii) additionally adjusted for height, log-transformed weight and TBLH BA. TBLH BA is adjusted for (i) age, gender, ethnicity, maternal education and paternal social class and (ii) additionally adjusted for height and log-transformed weight. Graphs show mean ORs ± 95% CIs for the association between each tertile and fracture risk (1 = lowest tertile, 3 = highest), calculated by logistic regression. The highest tertile was taken as the baseline category, and the p values are for the test for trend. TBLH BMC and TBLH BA were reduced to categorical variables (tertiles) after adjustment. The dotted line represents the null value of 1.
