The role of the endothelial nitric oxide synthase variants in the development of juvenile idiopathic arthritis and its clinical findings.

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
objectiveJuvenile idiopathic arthritis is the most common chronic arthritis in children and adolescents. Nitric oxide mediates autoimmune responses and plays a role in the etiology of numerous rheumatic diseases. Endothelial nitric oxide synthase regulates nitric oxide levels through catalyzing its production. Here, we evaluated the effect of eNOS rs1799983 and variable number tandem repeat variants on disease occurrence and clinical findings in Turkish juvenile idiopathic arthritis patients.
methodsOne hundred and eight participants, including 58 juvenile idiopathic arthritis patients and 50 healthy controls, were included in the study. eNOS rs1799983 and variable number tandem repeat variants were genotyped using polymerase chain reaction and/or restriction fragment length polymorphism. The genotype distribution of the patients was investigated according to their clinical and laboratory results. The results of the analyses were evaluated for statistical significance.
resultsThe eNOS genotype distributions did not differ between juvenile idiopathic arthritis patients and controls. Within the patient population, those carrying the rs1799983 GT/TT genotypes had higher body mass index, whereas those with the VNTR 4b/4b genotype had lower sedimentation rate.
conclusionOur study results suggest that the eNOS rs1799983 and variable number tandem repeat variants may play a role in juvenile idiopathic arthritis patients' clinical findings. These data need to be confirmed in different ethnic and larger sample groups.
