Patient information		Number of cases
Sex	Male	110
	Female	27
Age	≤ 60 years old	57
	> 60 years old	80
Mesh erosion time	≤ 6 mo	22
	> 6 mo	114
Type of hernia	Inguinal hernia	83
	Incision hernia	33
	Umbilical hernia	10
	Parastomal hernia	1
	Obturator hernia	1
	Abdominal wall strengthening	5
	Abdominal wall hernia not specified	5
History of abdominal surgery other than hernia repair		56
Symptoms of prior mesh infection		17
Condition of hernia after mesh erosion	Hernia recurrence	17
	Incisional hernia	3

The time of invasion was not specified in 1 case. Incisional hernia occurred in 1 case after umbilical hernia repair, and invasion occurred after secondary hernia repair. Due to various emphases in the case reports, it was impossible to judge whether the items not mentioned were negative, so only positive results were counted.
