Investigation of osteopontin levels and genomic variation of osteopontin and its receptors in Type 1 diabetes mellitus.
Article in Journal of endocrinological investigation, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundFailure in self-tolerance towards β-cells in diabetes mellitus (DM) pathogenesis involves a series of complex events that are governed by environmental and genetic factors. Considering the importance of osteopontin (OPN) in T-helper-1 (Th1) cells development, the aim of this study was to evaluate the serum level and gene polymorphism of OPN in Iranian Type 1 diabetic (T1DM) children.
methodsIn this case-control study, 87 T1DM children and 86 healthy ones were enrolled. Blood samples of both groups were checked for OPN level. The single nucleotide polymorphisms (SNP) were genotyped by RFLP analysis for OPN rs1126772, its receptor integrin α4 (ITGA4) rs 1449263, and CD44 rs8193.
resultsSerum levels of OPN in diabetic children were significantly higher in cases compared to the control group (p=0.023), but there was no significant relationship between OPN rs1126772 (p=0.79), its receptor integrin α4 (p=0.31), and CD44 rs8193 (p=0.45), and T1DM.
conclusionHigher amounts of OPN were seen in T1DM children. It is assumed that OPN might have inducing effects on T1DM development, particularly when genetically susceptible individuals are predisposed by an environmental insult. However, the 3 SNPs of OPN and its receptors did not show noticeable association with T1DM. The power of our study (~19%) was insufficient to observe any significant statistical difference between the groups; moreover, this study does not exclude the possibility of association of other SNPs of OPN and its receptors with this disease, and more studies are needed to clarify the issue.
