| Methods |
RCT Methods to control for contributory patient factors: none described |
|
| Participants |
Age: Group 1 (mean): 34 years Group 2 (mean): 36 years Gender: Group 1: 36.6% female Group 2: 39.3% female Type of incision: all participants had an upper midline incision ending above the umbilicus Type of surgery: all participants underwent vertical banded gastroplasty Contamination classification of included participants: all wounds were classified as clean‐contaminated Pre‐operative antibiotic use: all participants received antibiotic prophylaxis with 2 g of cefazolin Prognostic patient factors: all participants were diagnosed with morbid obesity Inclusion criteria: consecutive participants who underwent vertical banded gastroplasty for morbid obesity Exclusion criteria: none described |

| Interventions |
Comparisons reported: Group 1 Suture: PGA (multifilament, fast absorbable) Suturing technique: continuous, reinforced with "a few" interrupted sutures Closure method: mass Group 2: Suture: polyglyconate (monofilament, slowly absorbable) Suturing technique: continuous sutures, reinforced with "a few" interrupted sutures Closure method: mass Surgeon characteristics: all procedures were performed by a senior resident under supervision |

| Outcomes |
Incisional hernia: no definition provided Follow‐up duration: no group‐wise data provided; all participants were followed up for > 2 years Wound infection: discharge of pus, associated with fever and increased leukocyte count Wound dehiscence: no definition provided |

| Notes | — | |
| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Low risk | "The patients were allocated for closure with No.1 Dexon Plus or with No.1 Maxon by drawing a randomised card." |
| Allocation concealment (selection bias) | Unclear risk | Not clearly described |
| Blinding (performance bias and detection bias) All outcomes | Low risk | "All patients were followed up for more than 2 years by two surgeons who were blinded to the closure material used..." |
| Incomplete outcome data (attrition bias) All outcomes | Unclear risk | Not clearly reported |
| Selective reporting (reporting bias) | Low risk | Hernia (at least 1 year); dehiscence and wound infection outcomes all reported |
| Other bias | Low risk | The study appears to be free of other sources of bias |
