Electroacupuncture at Baliao points added to anorectal biofeedback for spinal cord injury-related neurogenic bowel dysfunction: a single-center prospective preference-allocated comparative study.

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
Background: Neurogenic bowel dysfunction (NBD) after spinal cord injury (SCI) remains difficult to manage in rehabilitation practice. Anorectal biofeedback targets defecatory coordination, whereas electroacupuncture at Baliao points may provide an additional sacral-region intervention. This study evaluated short-term between-group associations when Baliao electroacupuncture was added to anorectal biofeedback; it was not designed to isolate an electroacupuncture-specific effect. Methods: This single-center prospective preference-allocated comparative study enrolled 106 consecutive patients with SCI-related NBD between March 2024 and August 2025. Fifty-two received anorectal biofeedback alone and 54 received Baliao electroacupuncture plus biofeedback. The protocol scheduled 18 treatment sessions over approximately 6 weeks, with assessments at baseline, week 6, and week 12. Week 6 NBD score was the sole primary comparison. Covariate-adjusted models, propensity-score overlap weighting, mixed-effects models, and inverse-probability-of-follow-up weighting were supplemented by Results: Week 6 assessments were completed by 51/52 patients in the biofeedback group and 52/54 in the combined-treatment group. NBD score decreased more in the combined-treatment group (change, -5.2 ± 2.9 vs. -2.9 ± 1.9 points; adjusted difference, -2.1; 95% CI, -3.2 to -1.1; Conclusion: In this preference-allocated, non-randomized study, adding Baliao electroacupuncture to biofeedback was associated with a modestly larger short-term reduction in NBD score. Secondary and physiological findings were exploratory, and the design does not establish an electroacupuncture-specific contribution, causal superiority, or durable benefit. Confirmation requires prospectively registered, adequately powered randomized trials with attention-matched controls, blinded outcome assessment, and longer follow-up.
