Study on the association of COX-2 genetic polymorphisms with risk of gastric cancer in high incidence Hexi area of Gansu province in China.
Article in Molecular biology reports, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
To investigate the possible association of polymorphisms, cyclooxygenase-2 (COX-2) promoter region -899G>C, COX-2 codon 587G>A, with risk of gastric cancer in the high incidence Hexi area of Gansu province in China. Blood samples from 140 patients with gastric carcinoma and 125 normal persons were collected in Hexi area of Gansu province in China. Polymorphisms of COX-2 -899G>A and COX-2 587G>A were genotyped by PCR-TaqMan. For detection Helicobacter pylori infection, Warhin-Starry staining was used. Three kinds of polymorphisms of COX-2 -899G>C were GG, GC and CC. The frequencies in gastric cancer patients were 72.9, 21.4 and 5.7%, and the frequencies in controls were 84.0, 12.8 and 3.2%, respectively. COX-2 -899C carrier (GC + CC) increased risk of gastric carcinoma with an odds ratio 1.950 (95% CI: 1.067-3.586, P=0.029). The genotype of COX-2 587G>A polymorphism were GG, GA and AA. The frequencies in patients group were 86.4, 11.4 and 2.2%, and the frequencies in controls were 89.6, 9.6 and 0.8%, respectively. There was no significant difference between cases and controls in each genotype. Helicobacter pylori infection rate was 68.6% in patients group and 50.4% in healthy controls. Helicobacter pylori infection rate in gastric cancer patients was remarkably higher than that in normal people (OR: 2.147, 95% CI: 1.302-3.541, P=0.003). Stratification analysis was showed that COX-2 -899C carrier genotype with Helicobacter pylori infection was significantly higher in cases than that in healthy controls (OR: 4.000, 95% CI: 1.638-9.770). The polymorphism of COX-2 -899G>C could be a risk factor for gastric cancer in high incidence Hexi area of Gansu Province in China. COX-2 -899C carrier genotype and Helicobacter pylori positive infection may have a synergistic effect on gastric cancer in high incidence Hexi area of Gansu Province in China. However, the polymorphisms of COX-2 587G>A is no association with gastric cancer in the high incidence Hexi area of Gansu Province in China.
