Table 2.
Odds ratio and 95% confidence intervals of ultrasound imaging features predictive of a positive result from ultrasound-guided fine-needle aspiration biopsy (FNA). Other than cortical thickness in mm and hilum status categorized as normal or abnormal, none of the other ultrasound imaging features and measurements was significantly (p>0.3769) associated with a positive FNA.

| Stage T2 or lower (n=128) | ||||
| Cortical thickness in mm | 1.258 | 1.042 | 1.520 | 0.0172 |
