Biofeedback magnetic stimulation improves postoperative bowel dysfunction after rectal cancer surgery.
Article in American journal of translational research, 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
objectiveTo evaluate the clinical efficacy of biofeedback magnetic stimulation (BFMS) in the management of postoperative bowel dysfunction (PBD) after rectal cancer surgery and to identify independent predictors of treatment outcomes.
methodsA retrospective cohort study was conducted involving 158 patients who underwent low anterior resection between 2018 and 2023. Patients were divided into two groups: the observation group, consisting of 83 individuals, received BFMS; whereas the control group, comprising 75 individuals, underwent conventional rehabilitation. Defecation function, anorectal manometric parameters - including resting and pressure (RAP), maximum squeeze pressure (MSP), and maximum tolerated volume (MTV) - as well as Wexner scores and QLQ-CR29 quality-of-life scores were assessed at 1, 2, and 3 months postoperatively.
resultsAt 2 and 3 months postoperatively, the observation group showed significantly greater improvement in defecation function, anorectal pressure metrics, and quality of life scores compared to controls (P<0.05). The incidence of adverse reactions was comparable between groups (14.46% vs. 6.67%, P>0.05). Multivariate analysis revealed that anastomotic leakage, ultra-low rectal cancer, interspinous diameter, and treatment method were independent predictors of postoperative outcomes (P<0.05).
conclusionBFMS is a safe and effective therapeutic approach for improving bowel function and quality of life in patients with PBD after rectal cancer surgery. Anatomical and surgical variables may serve as important predictors of treatment response.
