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

This study analysed mRNA expression of two members of the methyl-CpG-binding protein family - MeCP2 and MBD2 - in human non-neoplastic (n=11) and neoplastic (n=57) breast tissue specimens using a quantitative real-time PCR method. We observed higher expression levels of MeCP2 mRNA in neoplastic tissues than in non-neoplastic tissues (P=0.001), whereas no significant differences for MBD2 were detected. When studying the relations between the most important clinicopathologic features of breast cancer and the mRNA expression level of both MBDs, we found that oestrogen receptor (OR)-positive breast cancer specimens contained higher levels of MeCP2 mRNA than did OR-negative cancers (P=0.005). Furthermore, we observed statistically significantly higher levels of MeCP2 in non-neoplastic tissues expressing high levels of OR as compared to those expressing low levels (P=0.017). Finally, using a linear regression model, we identified a statistically significant association between OR expression and MeCP2 mRNA expression in neoplastic and non-neoplastic breast tissue specimens (P=0.003). In conclusion, we were able to demonstrate for the first time that there exists a strong association between OR status and MeCP2 mRNA expression. Furthermore, we speculate that MeCP2, regulated by OR, plays a key role in the differentiation processes in human breast tissues.
