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.
