Table 3

Multivariate logistic analysis of the probability of identifying a carcinoma versus an adenoma by clinical, echographic features and cytologic category.

	Parameters entered in the model	OR	𝑃 value	Concordance percentage	𝑅2
All nodules (𝑛=54)	Ab altered (yes versus no)	15.43	.046	92.9%	0.56
	Multiple versus single nodule	78.94	.003
	Cytologic Category (AUS versus FL)	21.49	.023
Only solid nodules (𝑛=45)	Multiple versus single nodule	29.53	.005	85.9%	0.48
	Cytologic Category (AUS versus FL)	12.50	.044

AUS: atypia of undetermined significance; FL: follicular lesion.
