“…Besides MD, numerous studies have identified various factors potentially influencing FNA outcomes in thyroid nodules ( 10 , 12 – 16 , 18 , 28 – 30 , 32 , 33 ), including age ( 14 ), needle path ( 18 ), needle size ( 11 ), calcification ( 10 , 12 , 18 ), echogenicity ( 14 , 16 ), composition ( 13 ), shape ( 12 ), the depth of nodule ( 29 , 30 ), and Hashimoto thyroiditis ( 12 ) et al. However, these studies primarily focused on factors influencing non-diagnostic outcomes (Bethesda I or III), with few examining the potential factors impacting malignant outcomes in FNA of thyroid nodules.…”
