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

The 8-oxoguanine DNA glycosylase (OGG1) gene has been considered to be associated with cancer susceptibility. The OGG1 Ser326Cys polymorphism has been reported to be associated with pancreatic cancer (PC), but the published studies have yielded inconsistent results. For better understanding of the effect of OGG1 Ser326Cys polymorphism on PC susceptibility, a meta-analysis was performed. All eligible studies were identified through a search of PubMed, Excerpta Medica Database (Embase), Elsevier Science Direct, and Chinese Biomedical Literature Database before May 2013. The association between the OGG1 Ser326Cys polymorphism and PC risk was conducted by odds ratios (ORs) and 95% confidence intervals (CIs). A total of five case-control studies with 1,690 cases and 3,650 controls were eventually collected. Overall, we found that OGG1 Ser326Cys polymorphism was not associated with PC susceptibility (Cys/Cys vs. Ser/Ser: OR = 0.95, 95% CI = 0.80-1.14; Cys/Cys vs. Ser/Ser + Ser/Cys: OR = 0.95, 95% CI = 0.78-1.14; Cys/Cys + Ser/Cys vs. Ser/Ser (OR = 1.00, 95% CI = 0.89-1.12)). In the subgroup analysis based on ethnicity, source of control, sample size, and genotyping method, no significant association was found in any genetic models. This meta-analysis suggests that the OGG1 Ser326Cys polymorphism may not associated with PC susceptibility. Considering the limited sample size and ethnicity included in the meta-analysis, further larger scaled and well-designed studies are needed to confirm our results.
