Performance using sonographic features, clinicopathological characteristics and combined sonographic–clinical–pathological parameters to predict the high risk of recurrence of TNBCs.

Method	Sensitivity (%)	Specificity (%)	AUC (95%CI)	P value
US features	59.6	70.2	0.674 (0.573–0.774)	0.0006
Clinicopathology	76.6	53.7	0.678 (0.580–0.775)	0.0003
Combined	85.1	59.7	0.737 (0.644–0.829)	<0.0001

US, ultrasound; AUC, area under curve; CI, confidence interval.

Sonographic features include regular shape, posterior acoustic enhancement and without calcification; Clinicopathological characteristics include tumor size >2cm, histological grade III, Ki-67 ≥40% and presence of LNM.
