Fig. 3: Silhouettes estimate VAT/ASAT ratio, a metric of unfavorable fat distribution.

A Two-dimensional (2D) MRI projections and silhouettes of an age, sex, BMI, and waist circumference-matched pair of participants with drastic differences in abdominal fat distribution. While both participants have an elevated waist circumference for their sex- and BMI-group, participant 1 primarily has ASAT-driven central obesity, while participant 2 primarily has VAT-driven central obesity. B A linear model combining age and silhouette prediction markedly outperforms anthropometric models for the prediction of VAT/ASAT ratio (Supplementary Data 6). Error bars represent 95% confidence intervals obtained from bootstrapping with 1000 resamples. C Waist circumference is strongly correlated with silhouette-predicted VAT (VATSIL) and silhouette-predicted ASAT (ASATSIL) (R2 0.72–0.76), but nearly independent of silhouette-predicted VAT/ASAT (VAT/ASATSIL) (R2 0.07–0.20).
