TABLE 3.

Multiple regression analysis modeling insulin‐like peptide 3 (INSL3) and total testosterone (T) using the hormonal, anthropometric, and lifestyle parameters, as indicated

	INSL3			T
	Std. β	t	p‐Value	Std. β	t	p‐Value
Age	−0.204	−8.62	<0.001	−0.159	−8.09	<0.001
INSL3				0.320	17.71	<0.001
T	0.443	17.70	<0.001
SHBG	−0.259	−9.89	<0.001	0.539	28.16	<0.001
LH	−0.219	−7.56	<0.001	0.344	14.51	<0.001
FSH	0.068	2.31	0.021	−0.319	−13.19	<0.001
Smoking	−0.092	−4.59	<0.001	excl.	excl.	excl.
Alcohol	0.047	2.43	0.015	excl.	excl.	excl.
BMI	−0.044	−2.09	0.037	−0.111	−6.362	<0.001

Note: Waist circumference was not included in the analysis as being colinear with body mass index (BMI). Std. β is the standardized beta coefficient for the model with its t‐value and significance (p‐value). “excl.” indicates a parameter excluded through lack of statistical significance in the final optimal model.

Abbreviations: FSH, follicle‐stimulating hormone; LH, luteinizing hormone; SHBG, sex hormone‐binding globulin.
