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

The objectives of this study were to evaluate the influence of the -1087 single nucleotide polymorphism (SNP) on the gene expression of interleukin (IL)-10 and to identify transcription factors binding to this site in B cells. Using electrophoretic mobility-shift assays and nuclear extract from the DG75 B-cell line, we demonstrated that the Sp1 transcription factor bound to the -1087 G-allele of the IL-10 promoter and that the transcription factors PU.1 and Spi-B bound to both the G- and A-alleles. Transient transfections showed that lipopolysaccharide stimulation resulted in a 15-fold increase in promoter activity for the G-allele as compared to a 6-fold increase for the A-allele. Co-transfection with Sp1 expression vector in Sp1-deficient SL2 cells leading to Sp1 binding to the G-allele of the -1087 SNP resulted in increased IL-10 promoter activity. The results suggest a role for Sp1 transcription factor in the activation of IL-10 through the G-allele of the -1087 SNP in response to inflammatory signals.
