Association Study Between Metallothionein-3 Protein Polymorphisms and Autism.
Article in Neurotoxicity research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Genetic susceptibility to high mercury body burden has been suggested as an autism risk factor in children. Metallothionein III (MT3) is the brain-specific form of the metallothionein family, which plays a key role in metal metabolism. We therefore looked for genetic variations in the MT3 gene that might increase the predisposition to autism. DNA was extracted from 132 autistic children and 132 age and gender-matched unrelated controls. All the samples were analyzed for nine single nucleotide polymorphisms (SNPs) with minor allele frequency > 10% in the MT3 gene. The mRNA levels of MT3 in white blood cells were evaluated by real-time PCR. We did not detect any association between these MT3 polymorphisms and the mRNA levels of MT3. We did not detect any association between MT3 polymorphisms and autism risk. However, we detected four novel MT3 SNPs that are not in the human SNP database. The clinical importance of these SNPs needs further investigation. Our data suggest that MT3 gene polymorphisms are not associated with autism.
