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

purposeStudies on the performance of epigenetic-based biomarkers in colorectal cancer (CRC) are scarce and have shown contradictory results. Thus, we sought to examine the prognostic value of histone-modifying enzymes (EZH2, SETDB1 and LSD-1) and histone post-translational marks (H3K27me3 and H3K9me3) in CRC.

methodsA retrospective series of 207 CRC patients primarily submitted to surgery in a cancer center was included in this study. Clinicopathological data were retrieved. One representative paraffin block per case was selected for immunohistochemistry, including normal and CRC tissues whenever possible. The percentage of positive nuclear staining (digital image analysis) was used to classify patients into "low" and "high" expression groups for each biomarker. Correlations between immunoexpression levels, clinicopathological features and clinical outcomes [disease-specific (DSS) and disease-free (DFS) survival] were examined. Statistical significance was set at p < 0.05.

resultsCRC tissues showed significantly lower expression of SETDB1 and higher expression of the remainder four biomarkers compared to normal mucosa. High EZH2 expression correlated with disease recurrence/progression, whereas low LSD1 expression and high H3K9me3 and H3K27me3 expression were associated with more advanced stage. In multivariable analysis, cases with high LSD1 expression displayed significantly better DSS and DFS (HR 0.477, 95% confidence interval: 0.247-0.923) adjusted for pathological TNM stage.

conclusionEZH2, SETDB1, LSD1, H3K9me3 and H3K27me3 expression are altered in CRC and may play a role in colorectal carcinogenesis. LSD1 immunoexpression levels independently predicted patient outcome in this cohort. Further investigations, using larger series, are warranted to confirm its potential clinical value and unravel underlying molecular mechanisms.
