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

Cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) was widely accepted as a pivotal molecule in downregulating T-cell mediated immune responses. In this study we investigated the polymorphisms which would impact the CTLA-4 gene expression and function to assess the association with the risk of gastric cancer. 205 gastric cancer patients and 262 healthy controls were included in the case-control study. PCR and restriction fragment length polymorphism (RFLP) methods were performed to identify the +49A/G and promoter -1661A/G polymorphisms. The promoter -1772T/C polymorphism was detected by PCR amplification refractory mutation system (ARMS) technique. A significant difference was observed between case and control groups. The frequency of +49A/G polymorphism AG and -1661A/G polymorphism GG genotype were significantly higher in patients than in controls (OR = 2.15, OR = 1.88, respectively). No significant difference was found in the allelic frequency of -1772T/C polymorphism between cases and controls (P = 0.478). By the haplotype analysis, logistic regression showed the frequency of haplotype A (GAT) and D (AGT) in the case group revealed significant difference compared with in control group (OR = 2.00, P < 0.001; OR = 1.62, P = 0.043, respectively). Our findings implied the genetic variations within CTLA-4 gene would be a critical risk factor to the susceptibility of gastric cancer.
