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

backgroundNovel biomarkers are of particular interest for predicting cancer prognosis. This study aimed to explore the associations between enhancer of zeste homolog 2 (EZH2) and patient survival in various cancers.

methodsRelevant literature was retrieved from PubMed and Web of Science databases. Pooled hazard ratios (HRs), odds ratios (ORs), and 95% confidence intervals (CIs) were calculated.

resultsForty-nine studies (8,050 patients) were included. High EZH2 expression was significantly associated with shorter overall (hazard ratio [HR] 1.74, 95% CI: 1.46-2.07), disease-free (HR 1.59, 95% CI: 1.27-1.99), metastasis-free (HR 2.19, 95% CI: 1.38-3.47), progression-free (HR 2.53, 95% CI: 1.52-4.21), cancer-specific (HR 3.13, 95% CI: 1.70-5.74), and disease-specific (HR 2.29, 95% CI: 1.56-3.35) survival, but not recurrence-free survival (HR 1.38, 95% CI: 0.93-2.06). Moreover, EZH2 expression significantly correlated with distant metastasis (OR 3.25, 95% CI: 1.07-9.87) in esophageal carcinoma; differentiation (OR 3.00, 95% CI: 1.37-6.55) in non-small cell lung cancer; TNM stage (OR 3.18, 95% CI: 2.49-4.08) in renal cell carcinoma; and histological grade (OR 4.50, 95% CI: 3.33-6.09), estrogen receptor status (OR 0.15, 95% CI: 0.11-0.20) and progesterone receptor status (OR 0.30, 95% CI: 0.23-0.39) in breast cancer.

conclusionsOur results suggested that EZH2 might be an independent prognostic factor for multiple survival measures in different cancers.
