Data are presented as median (IQR) or n (%). Minor lacerations were defined as lacerations involving cutaneous tissue only. Major lacerations were defined as lacerations involving cutaneous tissue as well as deeper tissues. Variables are compared between patients with infectious complications and patients without infectious complications with Fisher’s exact test or Mann-Whitney U test
