Sacral neuromodulation in patients with refractory overactive bladder symptoms after failed Botulinum toxin therapy: Results in a large cohort of patients.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimsSacral neuromodulation (SNM) and Botulinum toxin A (BoNT-A) injections are well-known third-line treatment options in patients with refractory overactive bladder (OAB). Our aim is to evaluate the success rate of SNM in patients who received prior therapy with BoNT-A injections.
methodsAll patients with OAB symptoms referred for SNM between 2006 and 2019 were included. History taking and 3-day voiding diaries assessed the complaints and suitability for SNM. The success rate of SNM in patients who received prior BoNT-A was compared with BoNT-A naive patients. Success was defined as an improvement of 50% or greater in voiding diary parameters. Satisfaction was registered at their most recent visit.
resultsA total of 263 patients underwent SNM test stimulation, of which 75 (16 male/57 female) received prior BoNT-A and 188 (46 male/142 female) were BoNT-A naive. Success rate for SNM in BoNT-A naive patients was 72.9% and in BoNT-A patients 66.7% (p = 0.316). Success rate after ≤2 BoNT-A injections was 68.5%, compared to 61.1% after ≥3 injections (p > 0.05). Success rate in patients perceiving lack of efficacy of BoNT-A was 67.4% (p > 0.05), subjected to temporary CISC was 73.7% (p > 0.05) and with temporary effect of BoNT-A was 50% (p > 0.05). In 86% of BoNT-A patients the system was still activated and used to their satisfaction at their last follow-up visit (mean FU, 40.70 months).
conclusionSNM in patients with refractory OAB who failed prior BoNT-A is an excellent approach. The number of injections nor reason of BoNT-A discontinuation have predictive value for success with SNM.
