MKI67 and neoplasm: Between the Ki-67 high-level expression group and the Ki-67 low-level expression group, the odds ratio (OR) of tumour pathological grade (comparing grade III with grade I + II) for high-level Ki-67 expression was 5.291 with a 95% confidence interval of 1.166–24.010, and the OR of the λHU in the VP (increased 1 Unit) for high-level Ki-67 expression was 0.020 with a 95% confidence interval of 0.002–0.197 (Table 5).
