A meta-analysis on the association between three promoter variants of TNF-α and Crohn's disease.
Synthesis in Molecular biology reports, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Tumor necrosis factor-alpha (TNF-α) has been regarded as a candidate gene for Crohn's disease (CD) based on its inflammatory function in immune reaction and the clinical effectiveness of anti-TNF-α therapy. However, studies to date have reported inconsistent findings for the association between TNF-α and CD. The PubMed, EMBASE, and Medline databases were systematically reviewed from all English language publications up to April, 2011. A total of twenty-nine studies concerning the association between CD and the TNF-α promoter polymorphisms of -308G/A, -857C/T and -238G/A were identified, among of them only twenty-three studies match the inclusion criteria (including 3,843 cases and 6,260 controls) and were selected for the statistical test. We found that neither the G allele of -308G/A (OR 1.02, 95% CI 0.87-1.19, P = 0.84), C allele of -857C/T (OR 0.97, 95% CI 0.86-1.09, P = 0.57) and G allele of -238G/A (OR 0.91, 95% CI 0.70-1.18, P = 0.48), and nor their GG (OR 1.05, 95% CI 0.88-1.25, P = 0.59), CC (OR 0.98, 95% CI 0.86-1.12, P = 0.76) and GG (OR 0.92, 95% CI 0.70-1.21, P = 0.55) genotypes were associated with CD susceptibility, respectively. Our meta-analysis demonstrates that three promoter polymorphisms of TNF-α above may not confer susceptibility to CD.
