For Chinese men, combining belly fat measurements from a single CT slice at the L1/L2 level with BMI can accurately estimate total body fat, accounting for 83% of the variation seen in DXA scans.
Scientific Claim
In Chinese men, a prediction equation using L1/L2 abdominal QCT fat percentage and BMI explains 83% of the variance in total body fat percentage measured by dual-energy X-ray absorptiometry (DXA).
Original Statement
“L1/L2%fat 0.27 × L1/L2%fat + 0.43 × BMI + 5.76 0.83 2.55”

Assessment Explanation
The claim states a specific statistical measure (adjusted R-squared) from regression analysis, which is appropriate for observational data. 'Explains' accurately describes the predictive relationship without implying causation.
