Association of dietary index for gut microbiota and all-cause and cardiovascular mortality in patients with diabetes or prediabetes

Figure 1 Study flow chart.

Figure 2 Restricted cubic spline analysis demonstrates an association between gut microbiota dietary index and risk of all-cause and cardiovascular mortality in patients with diabetes or prediabetes. A: All-cause mortality; B: Cardiovascular mortality; y-axis indicates log hazard ratio, solid line indicates estimated hazard ratio, and shaded area indicates 95%CI; DI-GM: Dietary index for gut microbiota.

Figure 3 Mediation analysis of HbA1c and body mass index in the association of dietary index for gut microbiota with all-cause and cardiovascular mortality in patients with diabetes or prediabetes. A: Mediation analysis of HbA1c in all-cause mortality; B: Mediation analysis of body mass index (BMI) in all-cause mortality; C: Mediation analysis of HbA1c in cardiovascular mortality; D: Mediation analysis of BMI in cardiovascular mortality. BMI: Body mass index; DI-GM: Dietary index for gut microbiota.
