Lack of association between the TGF-β(1) gene and development of COPD in Asians: a case-control study and meta-analysis.

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
Abnormalities in the transforming growth factor-β(1) (TGF-β(1)) gene are thought to be linked to chronic obstructive pulmonary disease (COPD). We investigated the association between the single nuclear polymorphisms (SNPs) of TGF-β(1) and the risk of COPD in a case-control study and meta-analysis. We genotyped 160 cases and 177 control subjects in a local hospital using the Mass-Array(TM) Technology Platform and then tested the association of four SNPs in TGF-β(1) (rs6957, rs1800469, rs2241712, and rs2241718) with COPD. Plasma TGF-β(1) level measurement was performed later. A database covering all papers published up to October 30, 2010, was then reviewed. Statistical analysis was performed using Revman 5.0 and STATA 11.0 software. No association was found between TGF-β(1) gene SNPs and an increased risk of COPD in Asians. By meta-analysis, the link of two polymorphisms, rs1800469 and rs1982073, was investigated in seven and eight studies, respectively, involving 1,508 COPD patients and 2,608 control subjects. The results showed that there was no significant association between an increased risk of COPD in carriers of the T allele (TT+TC) versus the CC genotype in rs1800469 and rs1982073. In ethnic subgroup analysis, the risk of COPD associated with the rs1800469 T allele was not significantly elevated among Asians. TGF-β(1) gene polymorphisms are not associated with an increased risk of COPD in the Asian population.
