Multivariate Analysis: Oncologically Appropriate Initial Total Thyroidectomy

Variable	OR	95% C. I.	p value
Age > 45 years old	1.44	0.63 – 3.29	0.38
Female gender	0.35	0.13 – 0.98	0.04
Suspicious for papillary thyroid cancer	5.68	2.10 – 15.33	<0.01
Family history of thyroid cancer	2.66	0.99 – 7.10	0.06
TSH ≥ 2.5 (U/mL)	1.82	0.74 – 4.48	0.19
Frozen section	9.71	2.45 – 38.56	<0.01

Multivariate logistic regression was performed with variables carrying a p value ≤ 0.2 from univariate analysis. Variables shown in bold were significantly associated with oncologically correct initial total thyroidectomy. In addition to suspicious for papillary thyroid cancer, the other cytologic diagnosis were also included in the model except for AUS/FLUS which was dropped due to collinearity. None of the other cytologic diagnoses were significant. U = units, mL = millimeters.
