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

Mel-18 is a member of the polycomb group (PcG) of proteins, which are chromatin regulatory factors that play an important role in oncogenesis. This study was designed to investigate the clinical and prognostic significance of Mel-18 in colorectal cancer (CRC) patients. For this purpose, expression of Mel-18 mRNA was evaluated in 82 primary CRC and paired noncancerous mucosa samples by qRT-PCR and Western blotting. We found that overall Mel-18 mRNA expression in the CRC tissue was significantly lower than in the noncancerous mucosal tissue (p = 0.007, Wilcoxon matched-pairs signed-ranks test). Mel-18 was conversely correlated with the pathological classifications (p = 0.003 for T, p < 0.001 for N, and p = 0.015 for M classifications, respectively) and clinical AJCC stage (p < 0.001). Furthermore, CRC patients with a higher level of Mel-18 showed prolonged disease-free survivals (DFS) (p < 0.001). In multivariate analysis, the diminished Mel-18 expression may be a risk factor for the patients' 3-year DFS (HR = 1.895; 95 % CI 1.032, 3.477; p = 0.039). It was therefore concluded that the lower Mel-18 expression might contribute to the CRC development/progression.
