Table 4. Univariate and Multivariate Analysis.

Clinical variable	Univariate^a (95% CI)	Multivariate^b (95% CI)	P value
Age	1.05 (1.02-1.08)	1.04 (1.01-1.08)	0.005
Male Sex	2.57 (1.30-5.06)	2.26 (1.08-4.73)	0.031
Malignant cytology ^c	8.21 (2.57-26.25)	6.60 (2.02-21.58)	0.002

Logistic regression was used to calculate the odd ratios.

Multivariate logistic regression used forward selection of five most significant covariates in univariate analysis. Area under ROC curve was 0.751 (95% CI; 0.673-0.830).
