Neural Network‐based predicting values and the actual values of T2D‐related factors based on the species level profile of D1 with our marker species. (A) FBG, (B) BMI, (C) age, and (D) weight. Each T2D‐related factor value was fit by the corresponding NN‐based regression model using fivefold cross‐validation, and the R‐value (i.e., Pearson's linear correlation coefficient) between the real values and the predicted values was obtained by statistical calculation. BMI, body mass index; FBG, fasting blood glucose; T2D, type 2 diabetes
