When testing the upper body fat prediction equations in women, the average difference from DXA measurements was small (0.47%), with most predictions falling within a range of -6.43% to 7.38%.

For Chinese women, belly fat measurements from a CT slice at the L3/L4 level combined with BMI can predict upper body fat distribution with 86% accuracy compared to DXA scans.

When testing the belly fat prediction equations in men, the average difference from DXA measurements was small (1.31%), with most predictions falling within a range of -4.08% to 6.71%.

For Chinese men, combining belly fat measurements from a CT slice at the L1/L2 level with BMI can predict upper body fat distribution with 90% accuracy compared to DXA scans.

For Chinese women, using belly fat measurements from a CT slice at the L5/S1 level along with body weight can predict total body fat with 81% accuracy compared to DXA scans.

For Chinese men, belly fat measurements from the lowest CT slice can predict lower body fat with 65% accuracy, while for women, this prediction also requires age information and has 51% accuracy.
