Efficacy of Abdominal Acupuncture in Poststroke Constipation: A Systematic Review and Meta-Analysis With Trial Sequential Analysis.
Synthesis in Brain and behavior, 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
backgroundPoststroke constipation (PSC) is a prevalent and disabling condition that significantly affects patient quality of life. Although abdominal acupuncture (AA) has demonstrated potential therapeutic effects on PSC, its efficacy remains unclear. This meta-analysis evaluated the efficacy of manual AA (MAA) and abdominal electroacupuncture (AEA) combined with conventional therapy (CT) for PSC.
methodsA comprehensive literature search was conducted to identify randomized controlled trials comparing the effects of MAA + CT or AEA + CT versus CT alone in PSC treatment. Twelve eligible studies (n = 943) were selected. Primary (efficacy and time to first bowel movement [BM]) and secondary (stool shape) outcomes were evaluated. Trial sequential analysis (TSA) was performed to assess cumulative evidence reliability.
resultsBoth MAA + CT (relative risk [RR] = 1.26, 95% confidence interval [CI]: 1.13-1.40) and AEA + CT (RR = 1.28, 95% CI: 1.19-1.38) significantly improved efficacy compared with CT alone. Furthermore, MAA + CT (mean difference [MD] = -0.61, 95% CI: -1.02 to -0.19) and AEA + CT (MD = -0.32, 95% CI: -1.09 to -0.46) reduced the time to first BM, albeit evidence regarding stool shape was inconclusive due to significant heterogeneity. TSA demonstrated unclear cumulative evidence and thus could not determine AA efficacy compared with CT.
conclusionMAA + CT and AEA + CT may effectively improve PSC by enhancing efficacy and shortening the time to first BM. Given the limited number of studies, small sample sizes, and significant heterogeneity, further high-quality trials are required to confirm these findings and optimize the acupuncture regimen for PSC treatment.
