| Q | Std. of abdominal wall thickness (cm) | 0.80 [0.33, 2.30] |
| R | Visceral fat volume (cm3) | 2073.50 [5.94, 10322.78] |
| S | Subcutaneous fat volume (cm3) | 16528.55 [296.69, 33288.25] |
| T | Evaluated height of abdominal region (cm) | 34.46 [25.00, 40.50] |
a Each index represents its corresponding metric in a simpler form. A-G are considered as shape-related, G-L as location-related, and M-T as body-related metrics.
b Note that (1) the quantitative values of the shape-related metrics are only collected among the subjects with identified hernias; (2) the normalized horizontal location represents the relative position from left ASIS to right ASIS, the normalized vertical location represents the relative position from the level of left and right ASIS to xiphoid process; (3) the volumetric body-related metrics are evaluated over the vertical range with labeled abdominal walls, represented as T, i.e., the evaluated height of abdominal region.
