Prediction of change in UAE from baseline. a Discovery cohort, clinical parameters model; b Discovery cohort, clinical parameters + serum metabolite classifier model; c Validation cohort, clinical parameters model; d Validation cohort, clinical parameters + serum metabolite classifier model. The lines of identity are shown in grey, and the regression lines are shown in red. In the case of perfect prediction, the regression line would be equal to the line of identity
