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

Maspin is a serine protease inhibitor with tumor-suppressor activity. Maspin can suppress tumor growth and metastasis in vivo and tumor cell motility and invasion in vitro. Previous studies indicate that the loss of Maspin expression is closely linked to aberrant methylation of the Maspin promoter. We examined the promoter methylation status of Maspin in tumor and corresponding serum of breast cancer patients. In addition, protein expression of this gene was also assessed to determine possible correlation between promoter hypermethylation and gene silencing. Further, we investigated the correlation of Maspin expression with vascular endothelial growth factor (VEGF-A) and MTA1 expression. Maspin methylation was analyzed by methylation-specific PCR in 100 invasive ductal breast carcinoma patients' tumors and circulating DNA in a prospective study. Promoter hypermethylation was correlated with expression of the encoded protein in tumors by immunohistochemistry. Significant correlation was observed between promoter hypermethylation of Maspin (r = +0.88; p ≤ 0.0001) in tumors and paired sera. Significant association was found between Maspin promoter hypermethylation and loss of its protein expression (p = 0.01, OR = 3.1, 95% CI = 1.3-7.4). The expression of VEGF-A and MTA1 was lower in tumors with high Maspin expression compared to tumors with loss of Maspin expression. Our results indicate that aberrant promoter methylation is associated with loss of Maspin immunoreactivity in breast cancer tissues. Further, loss of Maspin expression is significantly correlated with increased expression of VEGF-A and MTA1.
