Fig. 3: Linear and non-linear associations of dietary fiber types and carbohydrate-to-fiber ratio with metabolic outcomes in the metformin group.

From: Longitudinal associations of dietary fiber and its source with 48-week weight loss maintenance, cardiometabolic risk factors and glycemic status under metformin or acarbose treatment: a secondary analysis of the March randomized trial

Linear associations of legume fiber with BMI (A), FBG (B) and 2hPPG (C); whole grain fiber with DBP (D); non-linear associations of carbohydrate-to-fiber ratio with AUC for serum insulin (E) and BMI (F) in metformin group. Abbreviations: BMI body mass index, DBP diastolic blood pressure, TFBG fasting blood glucose, 2hPPG 2-h postprandial plasma glucose, AUC area under the curve. For both linear and RCS regression, adjustments were made for fixed effects such as the duration of intervention, duration of diabetes, sex, age, and total energy intake. Additionally, the center and individual were adjusted as random effects.
