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

backgroundBladder spasm is a common side effect of urological surgery. Main treatment modalities include opioids or anticholinergic medication; however, bladder spasms still occur even after these interventions. Recent studies indicate that transcutaneous stimulation of the foot can result in 50% increase in bladder capacity in healthy adults, and inhibit bladder detrusor overactivity in spinal cord injured patients. In this study, we examined the effects of transcutaneous electrical stimulation of the foot on bladder spasms related symptoms.

methodsSixty-six male patients who underwent prostate or bladder surgeries due to benign prostatic hyperplasia or bladder diseases were randomly divided into two groups: the control group (n = 36) and the treatment group (n = 30). The control group received the routine postoperative care. The treatment group received daily transcutaneous electrical stimulation of the foot during 3 days after surgery; each time lasted for 60 min. All patients were evaluated by the Visual Analogue Scale for pain sensation, frequency of bladder spasm episodes, and a total score of bladder spasms symptoms.

resultsIn the control group, the patients with bladder surgery had a higher Visual Analogue Scale score than patients with prostate surgery (P = 0.024). In both treatment and control groups, the Visual Analogue Scale score, spasm frequency, and total score of bladder spasm symptoms decreased from day 1 to day 3 (P <0.001). The Visual Analogue Scale score at day 2, total score of bladder spasm symptoms at day 2 and day 3 were significantly lower in the treatment group than in the control group (P <0.05).

conclusionThese results provided preliminary evidence suggesting beneficial effects of stimulating somatic afferent nerves in the foot on postoperative bladder spasms.

trial registrationThe study was registered with Chinese Clinical Trial Registry on June 13 2016 ( http://www.chictr.org.cn/ ) (Identifier: ChiCTR-INR-16008635).
