Fig. 4: The results of peak postprandial blood glucose prediction (GLUmax) with the test set.

X scale—CGM-measured values, Y scale—predicted values. a Baseline model—solely carbohydrate content of the meal (carbs); b the model based on clinically available parameters (anthropometric, biochemical, lifestyle questionnaire, meal content, meal context, CGM data); c full model—clinically available parameters + microbial features.
