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

introductionVitamin D levels and genetic factors, vitamin D receptor (VDR) and Toll like receptor- 2 (TLR-2) gene single nucleotide polymorphisms (SNPs), determine susceptibility to pulmonary tuberculosis. We aimed to evaluate vitamin D deficiency, VDR and TLR-2 gene SNPs in tuberculous meningitis (TBM).

methodsThis case-control study included 130 subjects each in three arms (TBM, pulmonary tuberculosis and healthy control). This study was performed in a large tertiary care institution of North India. Subjects were enrolled from August 2013 to July 2015. Vitamin D levels were measured using enzyme immunoassay. SNPs in VDR and TLR-2 gene were assessed using polymerase chain reaction-sequencing method. TBM patients were followed for 6 months.

resultsVitamin D deficiency was significantly more common in TBM compared to controls and pulmonary tuberculosis (TBM versus controls p < 0.001; TBM versus pulmonary tuberculosis p < 0.001). The heterozygous (TC) and mutant (CC) genotypes of Taq1 VDR SNP were significantly associated with TBM as compared to controls [TC; p < 0.001, odds ratio (OR) = 3.53 (1.95-6.40); CC; p = 0.002 OR = 5.97 (1.89-18.84)]. The heterozygous genotypes were significantly associated with TBM as compared with pulmonary tuberculosis [p = 0.001; OR = 2.53(1.43-4.45)]. Heterozygous (TG) and mutants (GG) forms of Apa1 VDR SNPs were significantly associated with TBM compared to controls [TG; p = 0.001, OR = 2.86 (1.58-5.17), GG; p = 0.002, OR = 5.11 (1.80-14.54)] and pulmonary tuberculosis. There was no significant difference in the frequency of TLR-2 SNPs. No association was found between outcome of TBM and vitamin D deficiency, VDR or TLR-2 SNPs.

conclusionVitamin D deficiency and VDR polymorphisms are associated with the susceptibility of TBM.
