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

purposeThe -1237T/C polymorphism of the Toll-like receptor 9 (TLR9) gene has been implicated in the susceptibility of inflammatory bowel diseases (IBDs), but the results remain conflicting. We further investigated this association via meta-analysis. MATERIALS AND

methodsMultiple electronic databases were extensively searched until February, 2015. The strength of association was evaluated by calculating the pooled odds ratios (ORs) and 95% confidence intervals (CIs).

resultsA total of 2987 cases and 2388 controls from eight studies were analyzed. Overall, association was found between TLR9 -1237T/C polymorphism and the risk of IBDs when all the studies were pooled (recessive model, OR: 1.59, 95% CI: 1.02-2.47, p=0.04; homozygote comparison, OR: 1.62, 95% CI: 1.04-2.52, p=0.03; allele model, OR: 1.13, 95% CI: 1.00-1.27, p=0.05). Stratification by ethnicity indicated an association between TLR9 -1237T/C polymorphism and IBDs risk in Caucasians (recessive model, OR: 1.59, 95% CI: 1.02-2.47, p=0.04; homozygote comparison, OR: 1.62, 95% CI: 1.04-2.52, p=0.03; allele model, OR: 1.12, 95% CI: 1.00-1.27, p=0.05). When stratified by disease type, significant correlation were only found in the Crohn's disease subgroup (recessive model, OR: 1.69, 95% CI: 1.05-2.73, p=0.03; homozygote model, OR: 1.74, 95% CI: 1.07-2.82, p=0.02; allele model, OR: 1.15, 95% CI: 1.01-1.32, p=0.04).

conclusionThe present study suggested that the TLR9 -1237T/C polymorphism might act as a risk factor in the development of IBDs, particularly in Caucasians.
