Reproducibility of semiautomated body composition segmentation of abdominal computed tomography: a multiobserver study

Table 2 Model fit evaluated by Akaike information criterion (AIC) for three mixed effects models

Model	AMC	IMAT	VAT	SAT
A: Only general observer to observer variation	2240	1813	2594	2508
B: Only systematic variation between observers in how segmentation was performed	2247	1866	2635	2527
C: Full model (A + B)	2242	1815	2596	2510

Data are AIC values. Lower AIC values indicate better model fit
AMC abdominal muscle compartment, IMAT inter- and intramuscular adipose tissue, VAT visceral adipose tissue, SAT subcutaneous adipose tissue
