Sliding thresholds used for fine needle aspiration biopsy (FNAB) interpretation as test negative or positive. Four separate comparisons (A, B, C, D) evaluate the test accuracy of each FNAB diagnostic category to predict thyroid nodule malignancy. FNAB fine needle aspiration biopsyBack to article page
