TNF-β +252 A>G polymorphism and susceptibility to cancer.
Synthesis in Journal of cancer research and clinical oncology, 2013. 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
objectiveTumor necrosis factor-β (TNF-β) plays important roles in mediating cancer development. Many studies have argued possible associations of TNF-β +252 A>G polymorphism with different cancers. However, association between this most frequently studied polymorphism and susceptibility to cancer still remains controversial and ambiguous. The aim of this study is to determine the relationship of TNF-β +252 A>G polymorphism with cancer through meta-analysis.
methodsElectronic searches of several databases were conducted for all publications on the associations between this variant and cancer through October 2011. Odds ratios (ORs) with 95 % confidence intervals (95 % CIs) were used to access the strength of this association in random-effect model.
resultsThirty-three studies with 14,435 cancer patients and 10,583 healthy controls were included. In this meta-analysis, we detected statistically significant connections between this polymorphism and cancer risks [GG + GA vs. AA: OR = 1.24, 95 % CI = 1.02-1.51; GG vs. AA: OR = 1.43, 95 % CI = 1.05-1.95; G vs. A: OR = 1.28, 95 % CI = 1.28 (1.09-1.50)] in the overall ethnic population. Meanwhile, we detected significant associations in Asian population (GG + GA vs. AA), other population (GG vs. GA + AA), and Caucasian population (GG vs. AA, G vs. A) with the OR values being 1.21 (1.04-1.40), 1.64 (1.35-1.99), 1.65 (1.02, 2.65), and 1.39 (1.09-1.75), respectively.
conclusionsTNF-β +252 A>G polymorphism is positively associated with susceptibility to cancer. However, this study also suggests that more studies should be conducted to further confirm the associations between this variant and specific types of cancers.
