Predictive Ki-67 Proliferation Index of Cervical Squamous Cell Carcinoma Based on IVIM-DWI Combined with Texture Features

Table 6

The training set and testing set verify the predictive model’s diagnostic efficiency.

	Ki-67 PI ＜50% group (n)	Ki-67 PI ≥50% group (n)	Accuracy (%)	Specificity (%)	Sensitivity (%)	F-value	AUC
Training set	11	37	87.5	72.7	91.9	0.94	0.907
Testing set	5	17	90.9	80.0	94.1	0.94	0.899

PI, proliferation index; AUC, area under curve.
