Dangguijagyag-san for primary dysmenorrhea: A protocol for systematic review and meta-analysis of randomized controlled trials.
Article in Medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundPrimary dysmenorrhea is the most common gynecological disorder in women of reproductive age. In East Asia, traditional herbal medicines have been used for a long time to treat symptoms of primary dysmenorrhea. Dangguijagyag-san (DJS) is one of the most widely known traditional herbal medicine for primary dysmenorrhea. Although there was the previous systematic review of DJS, it had some limitations. To assess the effectiveness of DJS for primary dysmenorrhea and to update the previous review, this protocol was developed to conduct a systematic review and meta-analysis.
methodsWe will search the randomized controlled clinical trials of DJS for primary dysmenorrhea from inception to April 2019. The search database will be PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Oriental Medicine Advanced Searching Integrated System, Korean Traditional Knowledge Portal, Korean Medical Database, National Digital Science Library, and the China National Knowledge Infrastructure. Our 2 authors will perform the selection of studies, the extraction of data, and the quality assessment with risk of bias tool independently. To analyze the data, we will conduct the quantitative synthesis.
resultsWe will synthesize the data from selected studies and estimate the strength of the evidence DJS for the treatment of primary dysmenorrhea.
conclusionThis study will provide the scientific evidence of DJS. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration number is CRD42019130768.
