Lymph Node Metastasis and Extrathyroidal Extension in Papillary Thyroid Microcarcinoma in Cyprus: Suspicious Subcentimeter Nodules Should Undergo FNA When Multifocality is Suspected

Table 6

Prevalence and odds ratios (and 95% confidence interval) of LN metastasis and ETE by tumor size (≤5 mm, >5 mm), stratified by multifocality.
