ROI, regions of interest; 95% CI, 95% confidence interval (n = 69).
Three ROI were used to calculate visceral fat by DEXA scan. ROI 1 extends from S3/S4 vertebral space to L5/L6 vertebral space. ROI 2 extends from S3/S4 vertebral space to L3/L4 vertebral space. ROI 3 extends from L1/L2 to L4/L5 vertebral space. Correlation coefficient (r) and bias were calculated for each area using Spearman's rank and Bland-Altman test, respectively, to evaluate the relationship between visceral fat obtained by DEXA scan and dissected visceral fat pad measured by direct weighing. ROI 3 shows the strongest correlation and the lowest bias.
