A total of 132 patients with a Bethesda III/IV nodule were included in the Baseline Characteristics of the Study Population (Suspicious ultrasound characteristics were defined as presence of at least one of the following characteristics: marked hypoechogenicity (in a solid nodule), irregular shape (i.e., taller-than-wide), irregular margins, and/or presence of microcalcifications.The reference range for TSH is 0.4–4.0 mU/L.The reference range for fT4 is ∼10–25 pmol/L (sex and age dependent).[The median ultrasound nodule size was 34 mm (IQR 22–42) in benign and 36 mm (IQR 25–45) in borderline/malignant nodules (
