Efficacy and safety of transcutaneous electrical acupoint stimulation to assist bowel cleansing: study protocol for a single-center, single-blind, randomized controlled trial.

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
Introduction: High-quality bowel preparation is a crucial prerequisite for ensuring the effectiveness of colonoscopy. Although polyethylene glycol (PEG) remains the first-line cleansing regimen recommended by clinical guidelines, its practical application still faces challenges in achieving adequate bowel preparation rates. Transcutaneous electrical acupoint stimulation (TEAS) shows promise in enhancing intestinal motility through gut-brain-microbiota modulation. However, its role in the field of intestinal cleansing remains unclear. Methods and analysis: This randomized controlled trial will enroll 404 patients undergoing elective colonoscopy. The participants will be randomly allocated to either the TEAS group or the sham-TEAS group, in a 1:1 ratio. TEAS was applied to stimulate the Discussion: By bridging traditional acupoint therapy with quantifiable neurogastroenterological outcomes, this study aims to establish TEAS as a scalable adjunct in bowel preparation protocols.
