Evaluation of the association between vitamin D and lung cancer skin metastasis: A protocol for systematic review.
Article in Medicine, 2020. 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
backgroundThis study aims to investigate the association between vitamin D (VD) and lung cancer skin metastasis (LCSM).
methodsThe following databases will be retrieved from the beginning to the present of each database without language limitation: PUBMED, EMBASE, Cochrane Library, Web of Science, CBM, and CNKI. The reference lists of included trials and other sources will also be checked. Two researchers will independently undertake literature selection, data collection, and study quality evaluation. We will utilize a fixed or random-effect model to pool the data according to the heterogeneity test. The RevMan 5.3 software will be used to analyze the data and perform meta-analysis.
resultsThis study will summarize high quality study to explore the association between VD and LCSM.
conclusionThe findings of this study will help to judge whether there is association between VD and LCSM. ETHICS AND DISSEMINATION: No research ethical approval is required in this study, because it will only analyze published data. It is expected to disseminate through a peer-reviewed journal. STUDY REGISTRATION: osf.io/ph2au.
