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

objectiveSchizophrenia is a complex mental disorder with high heritability. The hypothalamic-pituitary-adrenal (HPA) axis, which is the stress system of the neuroendocrine system, is considered to impact psychotic disorders. We hypothesized that polymorphisms of HPA axis genes might be involved in the development of schizophrenia.

methodsA case-control study comprising 234 patients with schizophrenia and 399 matched healthy controls was conducted to investigate the association between the human melanocortin 2 receptor (MC2R) gene and schizophrenia risk. Seven tag single nucleotide polymorphisms (SNPs) (rs16941303, rs16941314, rs2186944, rs28926188, rs7230126, rs948322, and rs948331) of MC2R were genotyped by direct sequencing.

resultsNo significant associations were observed between any of the alleles, genotypes, or haplotypes examined within the MC2R gene and the risk of schizophrenia in the total group or in subgroups stratified by smoking or alcoholism. However, a subgroup analysis stratified by sex revealed that under the additive model, the C allele of the MC2R rs948331 SNP significantly decreased the risk of schizophrenia in females (odds ratio=0.18).

conclusionThe C allele of the MC2R rs948331 locus may be a protective factor, reducing the risk of schizophrenia in the female Han Chinese population.
