Core Tip

Core Tip: There exists a clear relationship between dietary index for gut microbiota and the risk of all-cause mortality and cardiovascular mortality in patients with diabetes or prediabetes. Because of its high clinical significance, it is necessary to have a deep understanding of this relationship. In this study, we provide a new perspective for the management of diabetes and provide a new direction for future research and clinical practice. Through further studies, new biomarkers and interventions may be discovered, thereby improving the quality of life and survival of diabetic patients.
