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

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)
c) 3–3.9	36 (35.64)	34 (33.66)	2 (1.98)
d) ≥4	50 (49.50)	42 (41.58)	8 (7.92)
Total	101 (100)	85 (84.16)	16 (15.84)

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
