Table 2.

Comparison of true positive, false positive, true negative, and false negative between single detection and combined detection (n (%)).

Detection methods	True positive (n)	False positive (n)	True negative (n)	False negative (n)
DCE-MRI	28 (70.00%) ∗	4 (10.00%)	5 (12.50%)	3 (7.50%)
Detection of serum HE4, Ki67, and HK10	24 (60.00%)#	5 (12.50%)	4 (10.00%)	7 (17.50%)##
Combined detection	36 (90.00%)	1 (2.50%)	2 (5.00%)	1 (2.50%)

Note. ^∗ An obvious difference in the number of true positives between DCE-MRI and the combined detection (x² = 5.000, P < 0.05). # indicates an obvious difference in the number of true positives between the combined detection and the detection of serum HE4, Ki67, and HK10 (x² = 9.600, P < 0.05). ## indicates an obvious difference in the number of false negatives between the combined detection and the detection of serum HE4, Ki67, and HK10 (x² = 5.000, P < 0.05).
