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
Glutathione S-transferase P1 (GSTP1) is an important enzyme playing critical roles in the phase II detoxification pathway. There were many studies investigating the association between GSTP1 gene Ile105Val polymorphism and gastric cancer risk, but studies from East Asians reported inconsistent findings. We performed a meta-analysis to investigate the association in East Asians. Published literature from PubMed and Chinese Biomedical Literature databases were searched for eligible publications. Pooled odds ratios (ORs) with 95 % confidence intervals (95 %CIs) were calculated using random or fixed-effect model according the between-study heterogeneity. A total of 12 studies with 2,552 cases and 5,474 controls were finally included into the meta-analysis. Meta-analysis of those 12 studies showed that there was an obvious association between GSTP1 Ile105Val polymorphism and gastric cancer risk in East Asians under three genetic models (for valine vs. isoleucine, OR=1.32, 95 %CI 1.05-1.66, P=0.015; for ValVal vs. IleIle, OR=2.00, 95 %CI 1.34-2.98, P=0.001; for the recessive model, OR=1.96, 95 %CI 1.35-2.83, P<0.001). Sensitivity analysis by removing one study at a time suggested the pooled results were stable under the three genetic models above. There was no risk of publication bias. In conclusion, the meta-analysis suggests that there is a strong evidence for the association between GSTP1 Ile105Val polymorphism and increased risk of gastric cancer in East Asians and contributes to increased risk of gastric cancer in East Asians.
