Table 1. Clinically relevant quantitative parameters for describing VH.

Category	Example quantitative parameters	Description	Significance
Location	Point distance from xiphoid process, umbilicus, linea alba, linea semilunaris, ASIS, and pubic symphysis	Relative location of VH with respect to bony landmarks and fascial boundaries	Reference for hernia classification [5]
Size/shape	Defect area	Area of abdominal wall fascial defect	Critical to selection of surgical techniques for hernia repair [9]
	Maximum dimensions	VH range on three orientations	Reference for hernia classification [5]
	Vhernia/Vabdomen	Ratio of volume size between hernia sac and abdominal cavity	A normalized indicator of hernia severity [8]
Mechanical	Compliance a	Ability of muscular tissues to yield elastically on a force	An indicator that correlates with ease of repair and recurrence rate [11]
