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

Lymphatic filariasis is mainly caused by the filarial nematodes Wuchereria bancrofti and Brugia malayi. Wolbachia, intracellular symbiotic bacteria in filarial parasite, is known to induce immune response predominantly through Toll-like receptor 2 (TLR2). This study was performed to investigate the association between polymorphisms of the TLR2 gene and susceptibility to asymptomatic bancroftian filariasis. A total of 142 unrelated asymptomatic bancroftian filariasis patients and 151 endemic normal controls in Tak province, Thailand were recruited into this study. The -196 to -173 deletion (del) polymorphism in the 5' untranslated region was investigated by allele-specific polymerase chain reaction. Two single nucleotide polymorphisms, +597 T>C and +1350 T>C, in exon 3 were identified by polymerase chain reaction-restriction fragment length polymorphism analysis. Furthermore, we analyzed the functional difference between the TLR2 -196 to -173 del and wild-type (wt) alleles using the luciferase reporter assay. All three polymorphisms were associated with a higher risk of asymptomatic bancroftian filariasis and were in strong linkage disequilibrium with each other. The TLR2 haplotype -196 to -173del/+597C/+1350C was strongly associated with an increased risk of asymptomatic bancroftian filariasis. The TLR2 -196 to -173 del allele had a significantly lower transcriptional activity than wt allele. The results of our study indicate that TLR2 -196 to -173 del, +597 T>C and +1350 T>C polymorphisms are associated with asymptomatic bancroftian filariasis in Thailand. Our functional study also supports this finding with respect to differential TLR2 gene expression by -196 to -173 del polymorphism.
