| Variable, n (%) | Group A (n = 86) | Group B (n = 172) | RR (95% CI) | p-value* |
|---|---|---|---|---|
| Any surgical complication | 14 (16.3) | 16 (9.3) | 1.75 (0.90 to 3.41) | 0.104 |
| PJI | 1 (1.2) | 0 (0.0) | 0.333 | |
| LFCN paresthesia | 3 (3.5) | 4 (2.3) | 0.689 | |
| GT avulsion | 2 (2.3) | 6 (3.5) | 0.722 | |
| Superficial wound infection | 7 (8.1) | 2 (1.2) | 0.007 | |

| Reoperation | 5 (5.8) | 4 (2.3) | 2.59 (0.68 to 9.91) | 0.165 |
Group A = patients with BMI ≥ 40 kg/m2
Group B = patients with BMI < 30 kg/m2
