Associations between the polymorphisms of GSTT1, GSTM1 and methylation of arsenic in the residents exposed to low-level arsenic in drinking water in China.
Article in Journal of human genetics, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
We carry out a study to analyze the relation between polymorphisms of GSTT1, GSTM1 and the capacity of arsenic methylation in a human population exposed to arsenic in drinking water. 230 randomly chose subjects were divided into four subgroups based on the arsenic levels, and then the associations between the polymorphisms of GSTT1, GSTM1 and methylation of arsenic were investigated. The levels of inorganic arsenic (iAs), monomethylated arsenic (MMA), dimethylated arsenic (DMA) and total arsenic (TAs) in urine were higher in males than that in females. Moreover, the levels of iAs and TAs in urine in the subjects with genotype of GSTM1(+) were significantly higher than those with GSTM1(-); the level of DMA in the subjects with GSTT1(+) and GSTM1(+) were higher than those with GSTT1(-) and GSTM1(-), although it is not statistically significant. Secondary methylation index (SMI) was significantly higher in the subjects with genotype of GSTT1(+) than those with GSTT1(-). The levels of TAs in urine, together with the genotypes of GSTT1/GSTM1 were associated with the levels of MMA and DMA. Our results suggested that the polymorphisms of GSTT1 and GSTM1 were associated with the methylation of arsenic, especially the levels of DMA and SMI.
