1 · What the graph read from 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.

2 · The registry

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

Studies examining the association between the cyclin D1 (CCND1) A870G (rs9344 G>A) polymorphism and esophageal squamous cell carcinoma (ESCC) have yielded inconsistent results. Here, we conducted a hospital-based case-control study in a Chinese Han population to assess the association between the CCND1 A870G polymorphism and ESCC. We then performed a meta-analysis to further investigate this association. We recruited 629 patients with ESCC and 686 cancer-free controls. Genotyping was performed with the polymerase chain reaction-ligase detection reactions (PCR-LDR) method. The meta-analysis was performed with the STATA 12.0 software. The case-control study showed no significant difference between the ESCC cases and controls in the allele frequencies or genotype distributions of the CCND1 A870G polymorphism. To obtain a more precise estimate of this relationship, we performed a meta-analysis of seven case-control studies involving a total of 2080 ESCC cases and 2833 controls. The meta-analysis suggested that the CCND1 A870G polymorphism is not associated with a risk of ESCC. A further subgroup analysis based on ethnicity also detected no association. This study suggests that the CCND1 A870G polymorphism is not associated with the risk of ESCC.
