Toward precision acupuncture: phlegm-dampness pattern as a candidate metabolic-microbial endotype in posterior circulation ischemic vertigo: a narrative review.
Review in Frontiers in neurology, 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
Posterior circulation ischemic vertigo (PCIV) denotes vertigo attributable to ischemia in the vertebrobasilar territory. It overlaps with the vascular vertigo categories of the Bárány Society diagnostic criteria and may indicate posterior circulation stroke or transient ischemic attack, so timely vascular evaluation is essential. In traditional Chinese medicine (TCM) theory, phlegm-dampness is regarded as a principal pathological product in vertigo, and pattern-based prescribing frequently targets it; whether phlegm-dampness pattern in PCIV corresponds to a biologically defined patient subgroup is unknown. This narrative review critically appraises the evidence behind that possibility. We searched PubMed, Embase, Web of Science, the Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang from inception to June 30, 2026. Direct clinical evidence in PCIV is limited to trials and meta-analyses of low certainty indicating that acupuncture, alone or as an adjunct, increases vertebrobasilar blood-flow velocity and improves symptom scores; transcranial Doppler velocity is not equivalent to tissue perfusion, and the composite "clinical effective rate" is a non-standardized outcome. Biomarker studies link phlegm-dampness constitution-assessed in non-PCIV cohorts-to dyslipidemia, low-grade inflammation, and gut microbiome alterations including depletion of
