Table 4 Association of benign USFNA nodule size and their corresponding surgical pathology diagnosis

From: The McGill Thyroid Nodule Score’s (MTNS+) role in the investigation of thyroid nodules with benign ultrasound guided fine needle aspiration biopsies: a retrospective review

Nodule Size (cm) Total n (%) Benign n (%) Malignant n (%)
a) 1–1.9 6 (5.94) 3 (2.97) 3 (2.97)
b) 2–2.9 9 (8.91) 6 (5.94) 3 (2.97)

Total 101 (100) 85 (84.16) 16 (15.84)
  1. Nodule sizes were determined pre-operatively by ultrasound and were subdivided into categories a) 1–1.9 cm, b) 2–2.9 cm, c) 3–3.9 cm, d) ≥4 cm
