  1. 26 metabolic traits from 14 metabolic classes, listed here, were associated with eGFR consistently across both diabetic and non-diabetic cohorts. Signs represent the directions of the regression coefficients in each diabetic (GenodiabMar, diabetics-TwinsUK, diabetics-KORA) and non-diabetic (TwinsUK, KORA, YoungFinns) cohort. Results were meta-analyzed for diabetic and non-diabetic cohorts separately. Association magnitudes are eGFR per 1-SD (log-transformed) concentration. For detailed list of associations of all 227 analyzed metabolic traits see Supplementary T2.
