Staging performance: probabilities used in the model

Mean
US:
Sensitivity0.5201
Specificity0.7993
FNA for suspected lymph nodes with US:
Sensitivity0.7216
Specificity1*
SLNB:
Sensitivity0.9420
Specificity1

* This value was assumed to be one since only one false positive was identified across all the studies included in the review of the accuracy of US+FNA
