Lack of Association Between the IL1B (-511 and +3954), IL1RN VNTR Polymorphisms and Tuberculosis Risk: A Meta-analysis.

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
backgroundSeveral recent studies have provided evidence that polymorphisms in the interleukin-1 (IL1) gene are implicated in tuberculosis (TB). However, results of different studies are inconsistent. The aim of this study was to perform a meta-analysis investigating the association of the IL1B (-511 and +3954) and IL1RN VNTR polymorphisms with TB risk.
methodsA systematic review of the English literature was conducted by searching Pubmed, Scopus, and ISI Web of Knowledge databases for relevant studies. Pooled odds ratios (OR) with 95 % confidence intervals (CI) were calculated using fixed effects models. Between-study heterogeneity and publication bias were also evaluated.
resultsNine case-control studies including 3327 participants were reviewed and analyzed. Our results did not indicate any association of the IL1B (-511 and +3954) and IL1RN VNTR polymorphisms with TB risk in the overall populations. The pooled OR of the IL1B -511 polymorphism was 1.09 (95 % CI 0.87-1.36) for the dominant model, 1.11 (0.89-1.38) for the recessive model, 1.15 (0.87-1.50) for the homozygote model, and 1.07 (0.94-1.23) for the allelic comparison model. ORs for the IL1B +3954 and IL1RN VNTR polymorphisms were similar. In subgroup analysis stratified by ethnicity, the results revealed no association between these polymorphisms and TB risk in black people, Asians, and Caucasians, respectively. We did not identify significant between-study heterogeneity across all studies, and there was no evidence of publication bias.
conclusionsOur results indicate there is a lack of association between the IL1B (-511 and +3954), IL1RN VNTR polymorphisms and TB risk.
