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

It is well documented that selenium (Se) is involved in the metabolism of glucose. However, whether Se supplementation could lower the risk of type 2 diabetes mellitus (T2DM) remains elusive. We aimed to evaluate the association between Se supplementation and the risk of T2DM by performing a meta-analysis. We searched the Pubmed, Embase, and Cochrane databases from January 1990 to November 2013 to identify randomized controlled trials (RCTs) that met pre-stated inclusion criteria. Reference lists of retrieved articles were also reviewed. Either a fixed-effects or, in the presence of heterogeneity, a random-effects model was used to calculate the pooled prevention effects. Four RCTs involving 20,294 participants were included in this meta-analysis. The combined relative risks (RRs) for subjects administered with Se compared with control groups were 1.09 (95 % CI: 0.99-1.20, p = 0.085). Omission of any single study did not change the overall risk estimates significantly. Meta- regression analyses showed almost no impact on the RRs of age and study length. No evidence of publication bias was observed. In conclusion, our findings do not support the routine application of Se supplementation for T2DM prevention in Caucasians. Larger studies are needed to investigate the effects of Se supplementation on T2DM prevention among various populations and further elucidate the impact of age and study length.
