1 · What the graph read from 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.

2 · The registry

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

TCF4 and GRM8, two significant genes involved in the normal nervous development and glutamate pathway, are thought to be involved in the pathogenesis of schizophrenia (SCZ). We aimed to explore the association of TCF4 and GRM8 gene polymorphisms with risk of SCZ. The rs8766 in TCF4 and rs712723 in GRM8 were selected for genotyping in a set of Iranian case-control samples including 215 patients and 220 matched healthy controls using polymerase chain reaction-restriction fragment length polymorphism. Although rs8766 increased the OR, we found that rs8766 allele and genotype frequencies were not significantly different between case and control groups and a significant association cannot be suggested for the selected SNP. However, allele C and genotype CC (allele C: OR 1.48, 95% CI 1.13-1.94; genotype CC: OR 1.71, 95% CI 1.09-2.68) of rs712723 polymorphism was found to have a significant association with risk of SCZ. Frequency of allele C (P = 0.003) and genotype CC (P = 0.017) was higher in the schizophrenic patients, while allele T (P = 0.003) and genotype TT (P = 0.028) frequencies were found lower in patients. Our findings indicate that rs712723 in GRM8 may play an important role in the pathogenesis of SCZ. However, our conclusion needs to be confirmed in other population.
