Subgroup analysis by approach (open compared with laparoscopic) for outcomes of surgical site infections, risk-adjusted against chronic kidney disease and serum albumin class prior to surgery

Complication	MBP only group	MBP+OABP group	Adjusted NNTa	Adjusted OR (95% CI)	P-value
Laparoscopic approach:	(N = 103)	(N = 108)
Surgical site infections, n (%):	13 (12.6)	1 (0.9)	8.1	0.061 (0.008, 0.482)	0.008
Superficial	8 (7.8)	1 (0.9)	14.6	0.111 (0.013, 0.916)	0.041
Organ space	5 (4.9)	1 (0.9)	24.8	0.163 (0.018, 1.460)	0.105
Open approach:	(N = 53)	(N = 47)
Surgical site infections, n (%):	12 (22.6)	6 (12.8)	9.6	0.475 (0.152, 1.482)	0.200
Superficial	8 (15.1)	3 (6.4)	11.4	0.378 (0.087, 1.648)	0.196
