Ancillary benefits of bladder chemodenervation for SCI neurogenic bladder.
Article in Spinal cord series and cases, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
STUDY
designCase series.
objectiveBladder chemodenervation is effective in treating neurogenic detrusor overactivity (NDO) in patients with neurogenic bladder due to spinal cord injury. Anecdotal reports also describe the improvement of non-bladder symptoms, specifically those related to autonomic dysreflexia (AD) and muscle spasticity. We conducted a study to further investigate this phenomenon.
settingUSA, Urban Tertiary Care Center.
methodsTwenty-one persons with SCI completed the study between March and December 2015. Mean age was 45 years (range 21-69). All were scheduled to undergo bladder chemodenervation with onabotulinumtoxinA 200 units to treat bothersome NDO refractory to oral medications. Each completed a questionnaire detailing symptoms unrelated to NDO immediately prior to the procedure, and again between 6 and 12 weeks after.
resultsAll patients reported improvement in NDO symptoms following chemodenervation. Ten patients with prior symptoms of AD reported improvement in AD symptoms after injection. Seventeen patients reported skeletal muscle spasticity in the 3-month period before chemodenervation. In the follow up period, only 14 patients reported having muscle spasticity. In aggregate, 12 of 21 patients reported improvement of non-bladder symptomatology following chemodenervation.
conclusionsChemodenervation of the bladder in patients with SCI can provide ancillary benefits in addition to mitigation of lower urinary symptoms. The mechanism may be related to dampening the bladder's ability to initiate noxious reflex responses.
