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

Background: Sacral neuromodulation (SNM) is a treatment used to manage urinary symptoms of both overactive bladder and non-obstructive urinary retention. The use of SNM in managing these symptoms has yielded positive results, contributing to a reduction in symptoms and an improvement in quality of life (QoL) for patients. This article aims to report on the electrical neurostimulation of sacral nerves to treat idiopathic non-obstructive urinary retention. Case Description: A 27-year-old female presented with chronic non-obstructive idiopathic urinary retention, using intermittent bladder catheterization, who did not respond to various treatments such as behavioral therapy, pelvic floor physiotherapy, and alpha-blockers. She underwent a sphincter injection of botulinum toxin type A. Due to the refractoriness of all previous treatments, electrical neurostimulation of the sacral nerves was proposed as an alternative. Two electrodes were implanted to stimulate the sacral nerves percutaneously in the foramina of S4 on both sides and connected to the neurostimulation system. Conclusion: After the procedure, the patient experienced a reduction in the average voiding residue (47% immediately postoperative and 29% after 1 year), a significant decrease in urinary tract infections and bladder catheterizations (50% reduction), along with improvements in urinary symptoms, abdominal discomfort, and a substantial enhancement in QoL.
