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

Urinary schistosomiasis is a parasitic disease caused by Schistosoma haematobium helminths. S. haematobium eggs may remain trapped within the bladder or the ureter walls, causing major pathological disorders in the urogenital system. The polymorphism rs1800925(C/T) of the IL13 gene promoter, which is functional, has previously been associated with susceptibility to S. haematobium infection. The aim of this study was to further our understanding and to determine whether, in the 5q31-q33 region, rs1800925 affects infection levels alone or in synergy with other polymorphisms. After sequencing the IL13 promoter and increasing the single-nucleotide polymorphism density, we performed a linkage disequilibrium analysis between rs1800925 and the other markers in a Malian population. Multivariate linear regression analysis and electrophoretic mobility shift assay (EMSA) were performed to characterized markers in linkage disequilibrium with rs1800925. An additional polymorphism, rs7719175, in the IL13 promoter was associated with controlling infection levels in multivariate analysis. The haplotype rs7719175T-rs1800925C was associated with high infection levels. EMSA indicated that rs7719175 affects the binding of transcriptional factors to the promoter region. Polymorphisms rs7719175 and rs1800925 have a synergistic role in the control of infection levels caused by S. haematobium and using them as a haplotype allows a better discrimination between infected subjects.
