p-value: p=<0.001
Ultrasound-measured visceral fat thickness correlates with visceral fat area and BMI but not with fatty liver or serum lipids, suggesting fatty liver disease is not strictly tied to increased abdominal fat.
Ultrasound visceral fat thickness may not aid fatty liver or lipid assessment; leaves open its added value beyond BMI for cardiometabolic risk.
Ultrasound examination is a simple and readily available method for the measurement of visceral fat thickness (VFT). According to the literature, VFT data correlate well with the computed tomographically determined “gold standard” values of visceral fat quantity, predicting cardiovascular risk of obesity. The probability of indicating the presence of the two major risk factors of obesity, namely, fatty liver and cardiovascular complications, was investigated by ultrasound. Ultrasound measurement of VFT and ultrasound liver attenuation were assessed in 201 patients and correlated with each other and with other parameters. A significant correlation (p < 0.001) was found between VFT and visceral fat area (VFA) measured by bioimpedance examinations and body mass index (BMI), but no correlation was seen between VFT and liver ultrasound attenuation as well as with serum lipid data. It was concluded that the presence of fatty liver disease is not certainly connected to the increase of abdominal fat.

Szebeni et al. (2011) conducted a cross-sectional in Obesity (n=201). Ultrasound-measured visceral fat thickness (VFT) was evaluated on Correlation between VFT and visceral fat area (VFA) measured by bioimpedance and BMI (p=<0.001). Ultrasound-measured visceral fat thickness significantly correlated with visceral fat area and BMI (p < 0.001), but showed no correlation with liver ultrasound attenuation or serum lipids.
