Association between serum vitamin D levels and the risk of kidney stone: evidence from a meta-analysis.
Synthesis in Nutrition journal, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 7 papers, 2 of them syntheses 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
backgroundMany epidemiological studies have conducted to evaluate the association between serum vitamin D levels and the risk of kidney stone. The aim of this study was to summarize the evidence from epidemiological studies between them.
methodsPertinent studies were identified by a search of PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure (CNKI) and China Biology Medical literature up to July 2015. Standardized mean difference (SMD) was conducted to combine the results. Random-effect model was used. Publication bias was estimated using Egger's regression asymmetry test.
resultsSeven articles involving 451 kidney stone cases and 482 controls were included in this meta-analysis. Our pooled results suggested that kidney stone patients had a significantly higher serum vitamin D level compared with controls [summary SMD = 0.65, 95 % CI = 0.51, 0.79, I(2) = 97.0 %]. The associations were also significant both in Europe [SMD = 0.35, 95 % CI = 0.17, 0.53] and in Asia [SMD = 1.00, 95 % CI = 0.76, 1.25]. No publication bias was found.
conclusionsOur analysis indicated that serum vitamin D level in kidney stone patients was significantly higher than that in non-kidney stone controls, both in Europe and Asia populations.
