Significant association between CYP1A1 T3801C polymorphism and cervical neoplasia risk: a systematic review and 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
Recently, many studies have been published to evaluate the correlation between the cytochrome P450 1A1 (CYP1A1) T3801C polymorphism and cervical neoplasia risk. However, the results remain inconclusive. To clarify this possible association, we conducted a systematic review and meta-analysis of published studies. Data were collected from the following electronic databases: PubMed, Embase, Ovid, ISI Web of Knowledge, Google Scholar, and Chinese Biomedical Database databases. The pooled odds ratio (OR) and its 95 % confidence interval (95 % CI) were used to assess the strength of this association. The pooled ORs were performed for the allele model (C vs. T), the homozygote model (CC vs. TT), the dominant model (CC/CT vs. TT), and the recessive model (CC vs. TT/CT), respectively. Finally, a total of 12 independent studies including a total of 3,724 subjects (1,912 cases/1,812 controls) were eligible for meta-analysis. Overall, there was a significant association between the CYP1A1 T3801C polymorphism and cervical neoplasia susceptibility (C vs. T, OR 1.32, 95 % CI 1.04-1.68, P = 0.02; CC vs. TT, OR 1.99, 95 % CI 1.19-3.35, P = 0.01; CC/CT vs. TT, OR 1.36, 95 % CI 1.02-1.81, P = 0.02; CC vs. TT/CT, OR 1.57, 95 % CI 1.23-2.02, P < 0.01). Meta-analysis of the ten studies on cervical cancer suggested a significant association between the CYP1A1 T3801C polymorphism and cervical cancer risk (C vs. T, OR 1.38, 95 % CI 1.05-1.82, P = 0.02; CC vs. TT, OR 2.06, 95 % CI 1.15-3.70, P = 0.02; CC/CT vs. TT, OR 1.45, 95 % CI 1.03-2.02, P = 0.03; CC vs. TT/CT, OR 1.56, 95 % CI 1.20-2.03, P < 0.01). In the stratified analysis by ethnicity, significant associations were also detected in some genetic models. This meta-analysis demonstrates a significant association between the CYP1A1 T3801C polymorphism and cervical neoplasia susceptibility.
