Extended Data Fig. 2: Separation of PPGRs to meals by engineered features.
From: Individual variations in glycemic responses to carbohydrates and underlying metabolic physiology
a: Delta glucose peak (relative peak value to baseline) (mg/dL) and return time (min) for different food combinations. CGM curves are extracted into different features and presented with mean and standard errors (the error bar indicates 2 standard errors). The x axis is different food combinations, and the y axis is the feature value. Bars are ordered by mean value. The number of CGM curves (each dot) is: rice 115, potatoes 92, bread 99, pasta 65, grapes 98, beans 46, mixed berries 53, rice+fiber 64, rice+protein 61, and rice+fat 60. Extracted CGM features are compared between different carbohydrate meals. Each participant was instructed to eat each meal at least twice on two different days. b: the scatter plot for three exemplar meals visualized with 2 relatively independent features. The x axis is time to peak (the slope from baseline to peak, mg/(dL*min)), and the y axis is delta glucose peak. Different colors indicate different meals. Each point is one CGM curve.
