Association of the CTLA-4 1722TC polymorphism and systemic lupus erythematosus: a systematic review and meta analysis.
Review in Medical journal of the Islamic Republic of Iran, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundCytotoxic T lymphocyte-associated antigen-4 (CTLA-4) is an important negative regulator of Tcell responses. The -1722TC polymorphism of the CTLA-4 gene may be associated with systemic lupus erythematosus (SLE) risk, but related results from previous studies have been inconsistent. We carried out a metaanalysis to assess this association more precisely.
methodsA systematic search through PubMed, Science Direct, and OVID, Iran doc, Iranmedex and SID (Scientific Information Database) databases was performed with the last search updated on December 30, 2011. The odds of ratio (OR) and its 95% confidence interval (95%CI) were used to assess the strength of the association. We evaluated both fixed and random effect models, depending on the presence of between-study heterogeneity. The analyses were conducted using STATA software, version 11.0.
resultsA total of 9 independent studies on the CTLA-4 gene -1722TC polymorphism and SLE, including 1422 cases and 1417 controls were used in this meta-analysis. In the present meta-analysis, we found a significant association between -1722TC polymorphism and SLE risk in the overall analysis (TT versus TC/CC: OR=1.18, 95%CI 0.84-1.66, p= 0.32; TT/TC versus CC: OR = 2.06, 95%CI 1.07-3.99, p= 0.03; TT versus CC: OR = 2.32, 95%CI 1.62-3.32, p< 0.001; TC versus CC: OR = 1.99, 95%CI 1.42-2.78, p<0.001; TT versus TC: OR = 1.2, 95%CI 0.86-1.66,p= 0.28; T versus C: OR = 1.22, 95%CI 0.91-1.64,p= 0.16). In the subgroup analysis by ethnicity, -1722TC polymorphism was significantly associated with SLE risk in Asian population.
conclusionThis meta-analysis suggests a significant association between -1722TC polymorphism and SLE susceptibility. Large-scale and well-designed case-control studies are necessary to validate the risk identified in the present meta-analysis.
