Multivariate logistic regression analysis for predicting malignant nodules.

Characteristic	OR	95% CI	P value
Gender	3.591	1.116–11.558	0.032
Hypoechogenicity	4.838	1.288–18.169	0.020
Shape (taller than wide)	5.478	2.161–13.887	0.000
VTI score ≥ 4	15.133	5.546–41.296	0.000
VTQ SWV > 3.10 m/s	5.891	2.417–14.362	0.000

Caption: OR, odd ratio; CI, confidence interval

Gender, hypoechogenicity, shape (taller than wide), VTI elastography score ≥ 4, and SWV > 3.10 m/s were found to be independent risk factors in predicting PTMC.
