Table 1 Ultrasound measurements

Measurement	Probe	Anatomical location	Method used for measurement
msA	Linear	Just below the xiphoid process of the sternum	Minimum distance between the fat-skin barrier and the anterior surface of the linea alba
MppA	Linear	Just below the surface of the xiphoid process of the sternum (same anatomical position as the minimum subcutaneous adiposity measurement)	Maximum distance between the posterior surface of the linea alba and the anterior surface of the peritoneum covering the liver
MsA	Linear	(A) 2 cm above the umbilicus and (B) 2 cm below the umbilicus	Maximum distance between the fat-skin barrier and the anterior surface of the linea alba
MiA	Convex	2 cm above the umbilicus (same anatomical position as maximum subcutaneous abdominal adiposity A)	Maximum distance between the posterior surface of the rectus abdominis muscle and the anterior wall of the abdominal aorta
MsSI	Linear	Just above the iliac crest on the mid-axillary line	Maximum distance between the fat-skin barrier and the anterior surface of the external oblique muscle
MsL	Linear	Level of L4/L5 directly over the lumbar erector spinae muscle	Maximum distance between the fat-skin barrier and the anterior surface of the lumbar erector spinae muscle

MsA minimum subcutaneous abdominal adiposity, MppA maximum pre-peritoneal abdominal adiposity, MsA maximum subcutaneous abdominal adiposity, MiA maximum intra-abdominal adiposity, MsSI maximum subcutaneous supra-iliac adiposity, MsL maximum subcutaneous lumbar adiposity
