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

objectiveNeuregulin1 (NRG1) gene is among the most promising candidate genes for schizophrenia. This gene is located on 8p22-p12, a region with a reported linkage to schizophrenia. Several studies have reported an association between schizophrenia and the 5' end polymorphisms in this gene. However, some studies have failed to confirm the role of NRG1 gene in the pathogenesis of schizophrenia. In the current study, we attempt to examine the association of SNP8NRG241930 from the NRG1 gene with schizophrenia in an Iranian population. It is noteworthy that there has been no report on the NRG1 association with schizophrenia in a population from the Middle East region. MATERIALS AND

methodsGenomic DNA samples were obtained via isolation from the peripheral blood cells of 95 unrelated subjects with schizophrenia and 95 matched healthy controls from southwest Iran. SNP8NRG241930 was genotyped by PCRRFLP using ScaI as a restriction endonuclease enzyme. Association of the SNP with schizophrenia was examined using the chi-square test. The frequency difference of alleles and genotypes between the two groups were compared. P≤0.05 was considered significant.

resultsStatistical analysis on the studied polymorphism showed that both case and control groups were in Hardy-Weinberg equilibrium. The frequency of high risk allele (G allele) was 72.6% in patients, while this number was 56.8% in controls. The genotype frequencies in the patient group were as follows: GG (54%), GT (38%) and TT (8%) vs. genotype frequencies in the control group of: GG (26%), GT (63 %) and TT (11%).

conclusionConsidering allele and genotype frequencies, a significant association was observed between schizophrenia and SNP8NRG241930. The current study adds weight to the idea that some functional polymorphisms could exist in the 5' end of the NRG1 gene which increase susceptibility to schizophrenia. This is the first time that supportive evidence shows an involvement of the NRG1 locus in schizophrenia in an Iranian sample population.
