Correlation matrix examining the relationship between subject BMI, metabolic endotoxaemia (LBP) and serum zonulin plus testosterone

	BMI (kg/m2)	Serum testosterone (nmol/L)	LBP (µg/mL)
Serum zonulin (ng/mL)	0.675**	−0.830**	0.609**
BMI (kg/m2)		−0.827**	0.470*
Serum testosterone (nmol/L)			−0.586*

Metabolic endotoxaemia was indirectly quantified by assessment of serum LBP levels, as previously described.^4–6

*p<0.05, **p<0.01.

BMI, body mass index; LBP, lipopolysaccharide binding protein.
