In addition, the multivariate regression analysis demonstrated that the rich blood supply to the tumor (OR = 0.124; 95% CI: 0.044–0.355; p < 0.001) was an independent risk factor for the Ki-67 index, and the erosion of the dorsum sellae bone (OR = 0.162; 95% CI: 0.057–0.469; p = 0.001) was independently related to the Ki-67 index (Table 2). Here, MKI67 is linked to neoplasm.
