Concomitant Detrusor and External Urethral Sphincter Botulinum Toxin-A Injections in Male Spinal Cord Injury Patients with Detrusor Overactivity and Detrusor Sphincter Dyssynergia.
Trial report in Journal of rehabilitation medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled it.
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
objectiveTo investigate the effects of concomitant injections of botulinum toxin-A (BoNT-A) into the detrusor and external urethral sphincter muscles in suprasacral spinal cord injured patients with detrusor overactivity and detrusor sphincter dyssynergia.
designAn open treatment trial with pre- and posttreatment evaluations. SUBJECTS: Male suprasacral spinal cord injury patients (n = 20) with neurogenic detrusor overactivity and detrusor sphincter dyssynergia who emptied their bladder by reflex voiding and were unwilling to increase the frequency of intermittent catheterization.
methodsCystoscopic guidance of 200 U BoNT-A injections into the detrusor muscle and 100 U into external urethral sphincter muscles were applied. The urodynamic parameters, voiding diaries and quality of life scores using Urinary Distress Inventory, Short Form (UDI-6) and Incontinence Impact Questionnaire, Short Form (IIQ-7) were compared.
resultsAll participants experienced a significant mean reduction in maximal detrusor pressure and maximal urethral pressure profile, and a mean significant increase in maximal cystometric bladder capacity 12 weeks after concomitant injections. Bladder diaries demonstrated persistently increased spontaneous voided volume, but no increase in post-void residual ratio, daily clean intermittent catheterization (CIC) frequency and diaper pad use from baseline to 24 weeks. UDI-6 scores were significantly improved at 4 and 12 weeks and IIQ-7 scores improved only at 12 weeks.
conclusionConcomitant detrusor and external urethral sphincter BoNT-A injections may decrease detrusor and urethral pressure without increasing postvoid residual ratio and diaper pad use. For spinal cord injury patients with neurogenic detrusor overactivity and detrusor sphincter dyssynergia who are unwilling, or for whom it is inconvenient, to increase CIC frequency and who want to preserve spontaneous voiding, this treatment may provide an optional alternative.
