Abbreviations. Mean absolute correlation: mean of the 10 absolute Pearson’s correlations from the metabolite correlation matrix. Estimate is the regression coefficient from the model BMI~age + sex + metabolite. Therefore, the estimates are the mean increase in BMI per 1 unit increase of the metabolite.
