Measure of association of incidence of infection with significant general characteristics

Variable	Measure of association
	Crude RR (95% CI)	Adjusted RR (95% CI)*	P value
Overall infections	0.77 (0.62–0.97)	0.78 (0.62–0.97)	0.029
Pfannenstiel incision	0.90 (0.72–1.12)	0.93 (0.74–1.15)	0.503
General anaesthesia	0.98 (0.75–1.26)	1.01 (0.78–1.32)	0.918

*Adjusted for Overall infections, Pfannenstiel incision and general anaesthesia.

RR, risk ratio; CI, confidence interval.
