Detect the disrupted brain structural connectivity in type 2 diabetes mellitus patients without cognitive impairment

Figure 3 Location of the 18 structural connections selected by forward feature selection. The blue line indicates that the connection strength is weaker in the type 2 diabetes mellitus (T2DM) group compared to the healthy control group. The red line indicates that the connection strength is stronger in the T2DM group. Thicker lines indicate larger statistical values, indicating greater significance in the observed differences between the groups. The process of the optimal model selection and the model evaluation metrics were included in the Supplementary Figure 2.
