Methods	Quasi-RCT; 5 parallel groups.
	Unit of randomization: individual.
Participants	Dates of data collection: not reported.
	Setting: Bursa, Turkey..
	Inclusion criteria: women undergoing CS due to acute fetal distress
Interventions	Ceftriaxone 1 g (N = 25) vs mezlocillin 2 g (N = 23) vs clindamycin 600 mg and amikacin 500 mg (N = 18) vs sulbactam ampicillin 1 g (N = 25) IV after clamping of the cord vs no treatment (N = 28)
Outcomes	Wound infection (redness, tenderness, pain and purulent discharge); UTI (renal angle tenderness, fever, dysuria and pyuria); endometritis (vaginal spotting, purulent discharge with fever and pain) plus positive cultures
Notes	Treatment groups combined.
	All wound infections were positive for coagulase negative staphylococcus

Risk of bias
Item	Authors’ judgement	Description
Adequate sequence generation?	No	“…according to the last digital of the patient’s file number…”
Allocation concealment?	No	“…according to the last digital of the patient’s file number…”
Blinding?	Unclear	Insufficient information provided.
All outcomes
Incomplete outcome data addressed?	Yes	No losses or exclusions were reported. It appeared to be an ITT analysis
All outcomes
Free of selective reporting?	Unclear	Insufficient information to judge.
Free of other bias?	Unclear	The 5 groups were comparable regarding maternal age, ruptured membranes, pelvic examinations, haemoglobin levels. Insufficient information to judge other aspects
Overall low risk of bias?	No	Quasi-RCT means it has high risk of bias.
