Genetic predisposition of variants in TLR2 and its co-receptors to severe malaria in Odisha, India.

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
Although the role of TLRs signalling in malaria pathogenesis is well established, contribution of individual TLR to clinical outcome of malaria still remains inconclusive. Given the importance of TLR2 and its co-receptors in recognising distinct structural forms of key malaria toxins and mediating innate immune response, it is essential to delineate their genetic contribution. Variants in TLR1 (I602S) and TLR6 (P249S) were genotyped by PCR-RFLP methods, and TLR2 (I/D) was genotyped by PCR in 200 samples each from uncomplicated malaria (UM) and severe malaria (SM). Further, SM was categorised into its sub-clinical groups (CM and NCSM or SOD and MODS) and analysed. The results showed the PP genotype of TLR6 (P249S) to be significantly more common in UM (P < 0.0001), whereas the 'SS' genotype was the risk factor for SM including its sub-clinical categories. The TLR1 (602S) and TLR2 (D) variants were significantly high in patients with CM; however, negative LD was observed between TLR2 and TLR6 in NCSM and MODS. Haplotype analysis showed significantly high frequency of I-I-S haplotype in all forms of subclinical SM and was associated with low parasite load in SM (P = 0.013). The haplotypes I-D-S and S-I-P were significantly high in SOD and CM, respectively. The TLR6 '249S' variant appeared to be the dominant determinant for genetic predisposition to SM and that its association with either TLR2 'D' or TLR1 '602S' modulates for CM development. The present study opens up several new avenues for their exploration and validation in future studies in different global settings for malaria.
