Lack of association between the G-660C polymorphism in the dopamine transporter gene (SLC6A3) and schizophrenia in the Iranian population.
Article in Indian journal of human genetics, 2012. 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
backgroundDopaminergenic system plays an essential role in the plasticity of the human brain. The dopamine transporter gene (SLC6A3) mediates active reuptake of dopamine from synapsis, terminates dopamine signals, and therefore, is implicated in a number of dopamine-related disorders like psychosis. Variations in the form of single nucleotide polymorphisms in the core promoter of the SLC6A3 gene are reported to be involved in the pathogenesis of schizophrenia. In this study, we also attempted to establish the possible role of the polymorphism G-660C in the SLC6A3 gene promoter in schizophrenia in a case-control study. MATERIALS AND
methodsThe allele and genotype frequency were analyzed in an Iranian cohort of 200 unrelated patients and 200 controls using polymerase chain reaction and restriction fragment length polymorphism.
resultsThe genotype frequency for case and control groups was GG 100%, GC 0%, CC 0%, and GG 100%, GC 0%, CC 0%, respectively. The C allele was failed in both groups.
conclusionOur data suggest clearly that there is no association between the -660G/C polymorphism and outcome of schizophrenia in the Iranian population.
