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

Gastric cancer is a multifactorial disease with the involvement of both genetic and environmental risk factors. Genetic variation in genes encoding cytokines and their receptors determine the intensity of the inflammatory response, which may contribute to individual differences in the outcome and severity of the disease. Transforming growth factor (TGF-β) signaling pathway plays an important role in the genesis and progression of tumors through regulating cell proliferation and differentiation. A hospital-based case-control study was conducted to investigate whether TGF-β1 -509 C/T polymorphism can modify the risk of gastric cancer. Seventy endoscopically and histopathologically confirmed gastric cancer patients and 100 age and sex-matched healthy controls were enrolled in the case-control study. TGF-β1 -509 C/T gene polymorphism was carried out by amplification refractory mutation system polymerase chain reaction (ARMS-PCR) method followed by agarose gel electrophoresis. Statistical analysis was applied to test for the significance of the results. The distribution of TGF-β1 genotypes at -509 C/T were CC 37.14%, CT 50%, and TT 12.86% in gastric cancer patients and CC 52%, CT 42%, and TT 6% in control subjects. The allelic frequencies of C and T were 0.621 and 0.379 in gastric cancer patients and 0.73 and 0.27 in control subjects, respectively. Our study imply that T allele of TGF-β1 -509 C/T genotypes may be a risk factor of genetic susceptibility to gastric cancer in south Indian population.
