[The association of XPD G312A polymorphism with lung cancer risk: a meta-analysis].
Synthesis in Zhongguo fei ai za zhi = Chinese journal of lung cancer, 2010. 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
BACKGROUND AND
objectiveIt has been proven that close relation was existed between XPD polymorphism G312A and lung cancer risk. However, some of the results are not consistent. The aim of this study is to explore the impact of DNA repair gene XPD polymorphism G312A on lung cancer risk.
methodsThe literatures eligible from PUBMED, EMBASE, CNKI and WANGFANG database were enrolled in the meta-analysis. Heterogeneity among combined studies was assessed. The pooled OR and 95%CI were calculated. The sensitivity analysis and the publication bias were evaluated by RevMan 5.0 and STATA 11.0.
resultsThere were 6554 cases and 8322 controls from 18 studies included in the meta-analysis. In total, individuals with 312A allele and 312AA genotype showed increased lung cancer risk (A vs. G: OR = 1.06, 95% CI: 1.00-1.12; AA vs. AG+GG: OR = 1.20, 95% CI: 1.06-1.36; AA vs. GG: OR = 1.19, 95% CI: 1.04-1.36). In Asians, individuals with 312AA genotype showed 6.15 fold and 6.20 fold increased lung cancer risk in recessive genetic model and homogenous contrast respectively (AA vs. AG+GG: OR = 7.15, 95% CI: 1.90-26.94; AA vs. GG: OR = 7.20, 95% CI: 1.91-27.15). In Caucasians, individuals with 312AA genotype showed a 15% increased lung cancer risk (OR = 1.15, 95% CI: 1.01-1.31).
conclusionXPD 312A allele is risk allele for lung cancer. Individuals with AA genotype have higher risk of lung cancer, especially in Asians.
