Comparative efficacy and safety of acupoint injection-related therapies for the treatment of intractable hiccup after stroke: a network meta-analysis.
Synthesis in Frontiers in neurology. 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
Objective: To systematically evaluate the effectiveness of various therapies (acupoint injection, acupuncture, etc.) in alleviating intractable hiccups after stroke through a comprehensive systematic review and network meta-analysis. Methods: We searched multiple databases up to July 2025 to find clinical randomized controlled trials on acupoint injection-related therapies for post-stroke intractable hiccups. Three authors independently screened studies. The quality of included studies was assessed according to PRISMA guidelines using the Cochrane RoB2 tool. Traditional meta-analyses of binary outcomes were performed with a fixed-effects model in Stata 17.0, complemented by prespecified subgroup analyses; comparative efficacy across interventions was subsequently estimated via network meta-analysis. Results: Twenty-one studies with 2,127 participants were included, and 17 studies with 1,658 participants were in the meta-analysis. The 95% confidence interval for the odds ratio of treatment effectiveness was (3.10, 7.63), indicating acupoint injection-related therapies were more effective than non-acupoint injection ones. The NMA of all 21 studies found that the combination of conventional acupuncture with auricular acupuncture exhibited the highest treatment efficacy (SUCRA 86.5%). This was closely followed by acupoint injection integrated with Western medical therapy (SUCRA 85.3%), while the regimen combining acupoint injection with standard acupuncture yielded a more modest efficacy profile (SUCRA 71.9%). However, the evidence quality of many interventions was low. Sensitivity analyses confirmed the findings' robustness, and no publication bias was detected. Conclusion: Acupoint injection-related therapies, particularly the combined application of acupuncture, acupoint injection, auricular therapy, and Western medications, demonstrate significant efficacy in alleviating intractable hiccups after stroke. This approach offers valuable reference and guidance for clinical treatment. Systematic review registration: https://www.crd.york.ac.uk/PROSPERO, Identifier CRD42024601310.
