Polymorphisms in chromosome region 12q13 and their influence on age at onset of type 1 diabetes.
Article in Diabetologia, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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/hypothesisA complex region covering numerous genes in 12q13 was first associated with type 1 diabetes in the Wellcome Trust Case-Control Consortium (WTCCC) study. Two studies performed in a white population have tested the association of polymorphisms within this region with age at onset of the disease, with seemingly contradictory results. We aimed at replicating three of the strongest signals in a group of patients with early and late disease onset.
methodsPolymorphisms rs773107, rs2292239 and rs10876864 were genotyped in 444 type 1 diabetic Spanish participants (age at onset 0-65 years) and 861 controls. The influence of single nucleotide polymorphisms (SNPs) on age at onset was tested through stratified and continuous analyses.
resultsrs773107 and rs2292239 were significantly associated with the disease, while rs10876864 showed a trend towards statistical significance in the whole population analyses. Comparison of early-onset patients to controls was significant for the three polymorphisms (allelic p < 0.006). Late-onset patients and controls did not reveal statistical differences. Analysis of age at onset in both rs773107 and rs2292239 showed differences between genotypes (p ≤ 0.002), alleles (p ≤ 0.013) and homozygotes for the risk genotype (p ≤ 4 × 10(-4)). Polymorphism rs10876864 showed trends towards statistical significance in the allelic frequencies (p = 0.051) and homozygotes for the risk genotype (p = 0.056). Subjects with risk genotypes had a disease onset between 2 and 5 years earlier than carriers of protective alleles. CONCLUSIONS/
interpretationWe replicate two of the previously studied associations in a Spanish population and find new evidence of the influence of the 12q13 region on age at onset of type 1 diabetes.
