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

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.
