Methods	RCT of TVT (Gynecare) vs TOT ('outside‐in' Monarc)
Participants	100 women Inclusion criteria: women with SUI or MUI with a predominant stress component, after failed conservative treatment Exclusion criteria: urge incontinence; previous mini invasive operation for SUI and the need for another concomitant surgical procedure SUI diagnosed with a positive cough test Urodynamic testing was only done in 5 patients (10%) Pure SUI: Group A: 38/50; Group B: 30/50 Preoperative characteristics similar between groups
Interventions	Group A: TOT (n = 50) Group B: TVT (n = 50)
Outcomes	Subjective cure at 14 and 46 months: success defined as a postoperative UISS < 8 and failure as ≥ 8 At 14 months At 46 months Vaginal tape erosion Voiding dysfunction De novo UUI Follow‐up at 3, 14 and 46 months Cough stress test was performed. Subjective cure and patient satisfaction recorded with aid of UISS and Detrusor Instability Score questionnaires with a specific question about satisfaction
Notes	Cystoscopy only performed in the TVT group Number available for follow‐up assessments: 14 months: Group A: 43/50; Group B: 43/50 At 46 months: Group A: 46/50; Group B: 47/50
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Quote: "This prospective randomized study included ... 100 patients were randomized either to the TVT or to the TOT"
Allocation concealment (selection bias)	Low risk	Quote: "randomization was performed with sealed and numbered envelopes"
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	No information
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	No information
Incomplete outcome data (attrition bias) All outcomes	Low risk	No evidence suggestive of attrition bias
