Efficacy of scalp acupuncture for post stroke dysphagia: A systematic review and meta-analysis of randomized controlled trials.
Synthesis in Medicine, 2026. 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
backgroundStroke persists as a paramount global health priority, maintaining persistently elevated incidence and mortality metrics across epidemiological registries. Post-stroke dysphagia, serving as a critical determinant of functional prognosis, imposes multidimensional burdens spanning aspiration pneumonia risk, nutritional compromise, and psychosocial well-being. This neurogenic deglutition disorder has consequently catalyzed clinical innovation in rehabilitation modalities, with scalp acupuncture emerging as a promising neuromodulatory intervention.
methodsWe conducted a systematic search of 8 databases for randomized controlled trials (RCTs) assessing scalp acupuncture treatment for post-stroke dysphagia. The primary outcomes included clinical efficacy, while the secondary outcomes comprised the Kubota Water Swallowing Test (WST), standardized swallowing assessment (SSA), videofluoroscopic dysphagia scale (VDS), and adverse events. Rigorous evaluation of potential biases within the selected studies was performed by the Cochrane Handbook (version 5.1.0) for systematic reviews of interventions. Heterogeneity among studies was addressed through sensitivity analysis.
resultsBased on data derived from 20 RCTs involving 1278 participants, the meta-analysis revealed significant clinical effective rate in the application of scalp acupuncture for post-stroke dysphagia [odds ratio = 4.45, 95% confidence interval (CI) (3.04, 6.51), P < .01], improvement in the Kubota WST [mean differences (MD) = -0.82, 95% CI (-1.04, -0.59), P < .00001], SSA [MD = -4.01, 95% CI (-4.59, -3.42), P < .00001], VDS [MD = -5.75, 95% CI (-8.33, -3.17), P < .0001], in comparison with the conventional rehabilitation protocols. Only one study reported adverse events.
conclusionCurrent evidence suggests that scalp acupuncture therapy may be an effective measure for post-stroke dysphagia.
