n	Comparison	Study design	Primary endpoint	Results [95% CI]	Adverse events
Study: Schellart et al. (2014) (e23)
193	MiniArc vs. TOT	randomized, non-blinded, non-inferiority design	Improved PGI-I score	MiniArc is not inferior to TOT after 3 years	13% serious adverse events with MiniArc, 11% with TOT
Study: Itkonen Freitas et al. (2022) (e24)
223	TVT vs. polyacrylamide hydrogel (bulkamide)	randomized, non-blinded, non-inferiority design	patient satisfaction questionnaire	bulkamide is inferior to TVT at 3 years*	43.5% complication rate for DVT, 24% for bulkamide*
Study: Dogan et al. (2018) (e25)
201	needle-free single-incision muscular sling (SIMS) vs. TOT	randomized, non-blinded, single-center	negative cough test	SIMS and TOT are comparably effective at 2 years (90% vs. 85% cure)	13% complication rate with TOT, 7% with SIMS* (SIMS significantly fewer symptoms)
Study: Holdø et al. (2017) (e26)
307	Burch colposuspension vs. TVT	non-randomized, non-simultaneous case series comparison	recurrent incontinence	revision rates at 12 years, 11% (colposuspension) vs. 2% (TVT)*	16% complication rate with colposuspension vs. 11% with TVT
Study: Lau et al. (2013) (e27)
100	TOT vs. TOT after vaginal prolapse net (Prolift)	non-randomized, prospective case series comparison	negative cough test	at 3–6 months, 86% cure rate for TOT versus 62% for TOT after vaginal mesh*	9% complication rate with TOT after vaginal mesh vs. 0% with TOT*
Study: Ward KL (2008) (e28)
344	Burch colposuspension vs. TVT	prospectively randomized, non-blinded multicenter trial	negative 1 hour pad test	at 5 years, 81% cure rate for colposuspension vs. 90% for TVT	more recto- and enteroceles with colposuspension*, complication rate 11% with colposuspension vs. 8% with TVT
Study: Karmakar (2017) (e29)
341	transobturator tape, inside-out vs. outside-in	postal follow-up of a randomized, controlled trial	patient satisfaction, measured with the PGI-I	71.6 % satisfaction and 14% improvement	in 7.96% new urinary incontinence surgery required, 4.5% erosion rate, 4.32% pain, in 1.4% therapy required
Study: Dejene et al. (2022) (e30)
334 601	follow-up of up to 15 years	cohort study	Frequency of of surgical revisions	at 10 years, 6.9%; at 15 years, 7.9% increased risk of surgical revision, in women aged 18–29 vs. ≥ 70 years	approx. 50 % of surgical revisions necessitated by tape erosion
