BW, body weight; AFW, abdominal fat weight; AFP, abdominal fat percentage; MW, weight of quadriceps (musculus rectus femulus, m. vastus intermedius, m. vastus lateralis, m. vastus medialis); LW, liver weight; KW, kidney weight; SW, spleen weight. Values above the diagonal are for correlation over both sexes together; values below the diagonal are for males and females separately. Bold values are significant at P < 0.0001. Asterisks mark different levels of significance: *P < 0.05, **P < 0.01, ***P < 0.001. Values in parentheses are not significant.
