Association between CTLA-4 gene polymorphism and ankylosing spondylitis: a case-control study.
Article in International journal of clinical and experimental pathology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
aimsThe aim of our study was to evaluate the association between CTLA-4 polymorphisms (+49A/G, -318C/T and CT60A/G) and ankylosing spondylitis (AS) susceptibility.
methodsA total of 120 AS cases and healthy controls, matched on the age and gender, were enrolled in the study. Polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP) were used to determine the gentypes of +49A/G, -318C/T and CT60A/G polymorphisms. Genotype distribution in control group was assessed by Hardy Weinberg Equilibrium (HWE) test. Odds ratio (OR) with 95% confidence interval (95% CI) were adopted to evaluate the relationship of CTLA-4 polymorphisms and AS susceptibility.
resultsIn our study, genotype distribution of the three polymorphisms in control group was consistent with the HWE (P > 0.05). The genotype analysis showed that AA genotype of + 49A/G polymorphism could increase the risk for AS (OR=2.357, 95% CI=1.127-4.930). Moreover, the frequency of A allele was also presented as a risk factor for AS. Additionally, AA genotype and A allele of CT60A/G appeared to be related with AS susceptibility (OR=2.610, 95% CI=1.047-6.510; OR=1.751, 95% CI=1.160-2.641). However, the T allele of -318C/T appeared to be a protective factor for AS (OR=0.383, 95% CI=0.228-0.643).
conclusionIn summary, there existed significant association between CTLA-4 gene polymorphisms and increased or decreased risk for AS.
