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

The maspin gene functions as a tumor suppressor in human breasts, and its expression is frequently lost during breast cancer progression. In vitro models of human breast cancer indicate that the loss of maspin expression is closely linked to aberrant methylation of the maspin promoter. We conducted a study on 30 archival ductal carcinoma in situ (DCIS) specimens to determine if aberrant methylation of the maspin promoter occurred in vivo, and whether it occurred early in breast cancer evolution. Healthy tissue obtained from reduction mammoplasty was used as normal control. Results from immunohistochemical analysis indicate that maspin expression is lost in a substantial fraction of DCIS specimens (57%). Bisulfite sequencing of DNA isolated from laser capture-microdissected normal and neoplastic ducts showed that loss of maspin expression was often, but not always, linked to aberrant methylation of the maspin promoter, suggesting that other mechanisms, in addition to aberrant methylation, participate and/or cooperate to silence maspin gene expression. Taken together, these results indicate that aberrant methylation of the maspin promoter is an early event in human breast cancer.
