| BMI | CT | Total fat | 0.77 | <0.001 | 0.80 | <0.001 | |

r represents Pearson’s correlation coefficient.
P-value for statistical significance computed using Pearson’s correlation test.
BMI = body mass index; CT = computed tomography; BIA = bioelectrical impedance analysis; VFA = visceral fat area.
