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

backgroundUNC5C and DCC, the netrin-1 receptors, belong to the functional dependence receptors family, which shares the ability to induce apoptosis in the absence of their ligands. Recently, two reports indicated that UNC5C and DCC methylation was closely associated with loss of gene expression in colorectal cancer. These results prompted us to examine the methylation status of the UNC5C and DCC genes in the colorectal carcinomas we surgically removed.

methodsThe methylation status of the UNC5C and DCC genes were examined in primary carcinomas and the corresponding normal tissues derived from 50 patients with colorectal cancer using quantitative methylation-specific polymerase chain reaction (qMSP). The correlation between the methylation status and the clinicopathologic findings was then evaluated.

resultsAberrant methylation of the netrin-1 receptor genes were detected in 41 of the 50 (82%) primary colon cancers, suggesting that the aberrant methylation of netrin-1 receptors was frequently observed in colorectal cancer. The clinicopathologic data were then correlated with this result.

conclusionsA significant difference was observed in the Dukes stage (p = 0.0438). Netrin-1 receptors might act as a tumor suppressor in colorectal cancers, and thus methylation might present a malignant potential in colorectal cancer.
