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
The aim of this study was to explore whether cytotoxic T lymphocyte antigen-4 (CTLA-4) +49 A/G, and -318 C/T polymorphisms confer susceptibility to asthma. A meta-analysis was conducted on the associations between the CTLA-4 +49 A/G, and -318 C/T polymorphisms and asthma using; (1) allele contrast, (2) the recessive model, (3) the dominant model, and (4) the additive model. Eight studies on the CTLA-4 polymorphisms and asthma involving 2,330 patients with asthma and 1,743 control subjects were included in this meta-analysis. The meta-analysis revealed an association between asthma and the CTLA-4 +49 A/G polymorphism under the dominant model in Asians (OR = 0.758, 95 % CI = 0.599-0.958, p = 0.020). Stratification by age indicated an association between the CTLA-4 +49 GG+GA genotype and asthma in children (OR = 0.690, 95 % CI = 0.497-0.957, p = 0.026), but not in adults (OR = 0.837, 95 % CI = 0.598-1.172, p = 0.300). Furthermore, stratification by atopy status indicated an association between the CTLA-4 +49 G allele and atopic asthma (OR = 0.639, 95 % CI = 0.464-0.881, p = 0.006), but not non-atopic asthma (OR = 0.706, 95 % CI = 0.385-1.294, p = 0.266). There was no association between asthma and the CTLA-4 -318 C/T polymorphism for the whole population, or when stratified by ethnicity, age, or atopy status. This meta-analysis demonstrates that the CTLA-4 +49 A/G polymorphism confers susceptibility to asthma in Asians, children, patients with atopy status, but there was no association between the CTLA-4 -318 C/T polymorphism and asthma susceptibility.
