1 · What the graph read from 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.

2 · The registry

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

purposeWe determined whether transfer of a primarily motor nerve (femoral) to the anterior vesicle branch of the pelvic nerve would allow for more effective bladder reinnervation than transfer of a primarily sensory nerve (genitofemoral). MATERIALS AND

methodsA total of 41 female mongrel dogs underwent bladder decentralization and then bilateral nerve transfer, or served as sham operated or unoperated controls. Decentralization was achieved by bilateral transection of all sacral roots that induced bladder contraction upon electrical stimulation. Retrograde neuronal labeling dye was injected in the bladder 3 weeks before sacrifice.

resultsIncreased detrusor pressure after direct stimulation of the transferred nerve, lumbar spinal cord or spinal root was observed in 12 of 17 dogs with genitofemoral nerve transfer and in 9 of 10 with femoral nerve transfer (mean ± SEM 7.6 ± 1.4 and 11.7 ± 3.1 cm H2O, respectively). Mean detrusor pressure after direct electrical stimulation of transferred femoral nerves was statistically significantly greater than after stimulation of transferred genitofemoral nerves. Retrograde labeled neurons from the bladder observed in upper lumbar cord segments after genitofemoral and femoral nerve transfer confirmed bladder reinnervation, as did labeled axons at the nerve transfer site.

conclusionsWhile transfer of a mixed sensory and motor nerve (genitofemoral) or a primarily motor nerve (femoral) can reinnervate the bladder, using the primarily motor nerve provided greater return of nerve evoked detrusor contraction. This surgical approach may be useful to achieve bladder emptying in patients with lower motor spinal cord injury.
