Efficacy of transcutaneous electrical acupoint stimulation for the treatment of gastrointestinal dysfunction in patients after cardiac surgery with cardiopulmonary bypass: study protocol for a superiority, single-centre, single-blind, randomised controlled clinical trial.
Article in BMJ open, 2025. 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
objectiveGastrointestinal dysfunction is one of the most frequent complications in patients after cardiac surgery with cardiopulmonary bypass (CPB). It can seriously affect the patient's quality of life, increase the length of hospitalisation and in severe cases trigger cardiac arrest. This single-centre randomised controlled study aims to investigate whether transcutaneous electrical acupoint stimulation (TEAS) can effectively relieve gastrointestinal discomfort and improve the quality of life of patients after cardiac surgery. METHODS AND ANALYSIS: A total of 426 patients after cardiac surgery with CPB will be randomly assigned to the control group or intervention group (1:1 ratio) to receive either acupressure or TEAS for 3 days. The patients will be recruited from the Department of Cardiovascular Surgery of Nanfang Hospital. The primary outcome is the time of the first postoperative anal defecation, the secondary outcomes include the first postoperative anal exsufflation time, the number of bowel sounds, the proportion of postoperative laxatives used in the two groups, abdominal girth, stool frequency per day and length of postoperative hospital stay. ETHICS AND DISSEMINATION: The procedures have been approved by the Guangdong Regional Medical Ethics Committee of Nanfang Hospital (NFEC-2023-404) and conformed to the Declaration of Helsinki. Written informed consent will be obtained from all the participants. Results will be disseminated through workshops, peer-reviewed publications and conferences.
