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

aims/hypothesisPlasma cell membrane glycoprotein 1 (PC-1) inhibits insulin signalling by direct interaction with the insulin receptor alpha subunit. This inhibition is enhanced by the minor Q allele of the K121Q polymorphism (rs1044498) in the gene (ENPP1) encoding PC-1. This polymorphism has been studied in relation to insulin resistance, type 2 diabetes and obesity in several populations with conflicting results. We assessed the impact of the ENPP1 K121Q polymorphism on type 2 diabetes, obesity and quantitative metabolic traits in 7,333 Danes. SUBJECTS AND

methodsThe K121Q polymorphism was genotyped in the population-based Inter99 study cohort (5,961 subjects) and in a group of 1,386 patients with type 2 diabetes. All subjects were Danish whites.

resultsNo significant associations with type 2 diabetes or related quantitative metabolic traits, including measures of insulin resistance, were detected. However, a meta-analysis of the present and published studies revealed an association with type 2 diabetes (odds ratio per Q allele, 1.17 [95% CI 1.10-1.25], p=1x10(-6)). In case-control studies comparing subjects of different BMI strata, we observed a putative association of the codon 121 QQ genotype with being overweight (BMI>25 kg/m(2); odds ratio 1.63 [95% CI 1.09-2.46], p=0.015), an association not observed when comparing other levels of BMI or when analysing BMI as a quantitative trait. CONCLUSIONS/

interpretationIn a meta-analysis, the ENPP1 codon 121 Q allele associates with type 2 diabetes. However, a similar association was not found in the present study of Danish white subjects. The effect of this variant on obesity in Danish subjects is contentious and further study is needed.
