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

backgroundPromoter hypermethylation is an important epigenetic mechanism in the regulation of several key modulators of prostate carcinoma progression. Recent studies suggest that the polycomb-group (PcG) protein BMI1 may have an impact on epigenetic regulation of several targets, including the CDKN2a locus.

methodsIn this study, we investigated the association of BMI1 expression, promoter methylation of CDKN2a (p16(INK4a) and p14(ARF)) and TMS1 with pathological variables (Gleason score, TNM stage, perineural invasion) in prostate cancer (PCa).

resultsMethylation of p16(INK4a) and p14(ARF) revealed an inverse association with Gleason score 7b and Gleason score 6. No significant association could be demonstrated for BMI1 -overexpression and promoter methylation of p16(INK4a), p14(ARF) and TMS1 as well as pT category.

conclusionsOur data suggest that the CDKN2a locus is a switch in PCa with methylation of p16(INK4a) being a marker for more aggressive tumours of Gleason score 7b, but no association with BMI overexpression was observed.
