Chinese herbal medicine Yanghe decoction for ankylosing spondylitis: A protocol for systematic review and meta-analysis.
Article in Medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundChinese herbal medicine is a commonly used traditional treatment for ankylosing spondylitis (AS). Among them, Yanghe decoction (YHD) has an obvious effect in relieving the symptoms of AS, but its efficacy is still controversial. The purpose of this study is to systematically evaluate the effectiveness and safety of YHD in the treatment of AS patients.
methodsFrom the establishment to September 2020, we will search a total of 7 electronic databases including PubMed, Cochrane Library, Embase, CNKI, VIP, WanFang, and the Chinese SinoMed Database. Two independent reviewers will search the database for relevant randomized controlled trials (RCTs), extract data, and evaluate the quality of the included RCTs. Data analysis will be processed by RevMan V.5.4 software.
resultsThe results of this systematic review will be published in a peer-reviewed journal.
conclusionThis study will provide evidence for the effectiveness of YHD in treating patients with AS.
