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

Type 2 diabetes mellitus (T2DM) is one of causes of mortality and morbidity in Moroccan population. The identification of genes implicated in this disease can help to found a specific treatment and to improve the quality of life for type 2 diabetic patients. In this study we analyze the association between a polymorphism (-308G>A) of TNF A promoter gene and T2DM in Moroccan patients. Five hundred and fifty-one individuals (307 patients with T2DM and 244 controls) were genotyped for this polymorphism by PCR-RFLP. This association was further reconsidered by a meta-analysis on 21 studies including 8,187 cases and 7,811 controls. We found that in Moroccan patients the -308A allele is strongly associated with T2DM (p = 0.000002; odds ratio 1.79, 95 % confidence interval 1.41-2.28). Based on our meta-analysis, there was no significant association detected between the TNF A -308G>A polymorphism and risk for T2DM. Our results suggest that the -308G>A polymorphism is a genetic risk factor for the development of T2DM in Moroccan population. On the other hand the meta analysis results led to controversial conclusions in other ethnicities.
