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

Numerous studies were published to investigate the relationship between the glutathione S-transferase T1 (GSTT1) null genotype and risk of gastric cancer in Asians, but the conclusions from those studies were conflicting. To get a more precise estimation on the possible association, we performed a meta-analysis of published data. A comprehensive literature was conducted and 27 case-control studies with 14,905 individuals were finally included, involving a total of 6,270 cases and 8,635 controls. The strength of the association between GSTT1 polymorphism and gastric cancer risk was estimated by calculating the pooled odds ratio with its 95 % confidence interval (95 % CI). A meta-analysis of total 27 studies showed that GSTT1 null genotype was obviously associated with increased risk of gastric cancer in Asians (random effect odds ratio (OR) =1.29, 95 % CI 1.16-1.44, P OR<0.001). A subgroup analysis of 14 studies with large sample size also showed an obvious association between GSTT1 null genotype and increased risk of gastric cancer in Asians (fixed effect OR=1.14, 95 % CI 1.06-1.23, P OR=0.001). In conclusion, the meta-analysis suggests that null genotype of GSTT1 contributes to increased risk of gastric cancer in Asian population.
