Differences in testosterone levels in perianal diseases: A comparative study of abscesses and fistulas

Table 5 Multivariate linear regression analysis of testosterone levels in the patients with perianal abscess (n = 64)

Predictor	B	SE	β	t value	P value	B diff (95%CI)	VIF
Constant	14.995	2.138		7.014	< 0.001	10.71-19.28
WBC (109/L)	-0.565	0.160	-0.441	-3.540	< 0.001	-0.885 to -0.245	1.165
BMI	-2.879	1.088	-0.298	-2.647	0.011	-5.058 to -0.700	1.138

Model summary: R² = 0.377, adjusted R² = 0.300, F (7, 56) = 4.851, P < 0.001. Multicollinearity: All variance inflation factor values were < 1.2, indicating no substantial multicollinearity. 95%CI: 95% confidence interval; VIF: Variance inflation factor WBC: White blood cell; BMI: Body mass index.
