Wajid 2015.

Methods	It is a descriptive case series. 300 participants were selected by non‐probability, consecutive sampling and were divided into 2 groups randomly by using lottery method.
Participants	Clinically reducible inguinal hernia.
Interventions	Lichtenstein repair vs sutureless repair.
Outcomes	Hematoma and postoperative pain within 7 days.
Notes	The method of this study is not specific and comprehensive enough: the full text did not tell us whether the sutureless repair group had some kind of glue applied. We have tried to contact the authors but without any answer. We are not sure whether this study fulfilled the inclusion criteria.
