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

purposeThe CpG island methylator phenotype (CIMP), important for carcinogenesis, is a predictor of prognosis and chemotherapy sensitivity in colorectal cancer (CRC). However, there is a lack of consensus on CIMP markers, and thus, more comprehensive methylation markers are required to reliably predict the clinical outcomes. This study aimed to clarify the effects of genome-wide DNA methylation status on clinical outcomes in patients with metastatic CRC (mCRC) treated with epidermal growth factor receptor (EGFR) inhibitors.

methodsWe enrolled 241 patients with mCRC, who received chemotherapy plus EGFR inhibitors as a first-line treatment. We analyzed the incidence and clinicopathological characteristics of highly methylated CRC (HMCC) and associations between genome-wide DNA methylation status and response rate (RR), progression-free survival (PFS), and overall survival (OS).

resultsIn total, 169 patients were included in the final analyses. The frequency of HMCC was 8.9% (15/169). The characteristics of patients with HMCC included right-sided primary tumor location (P = 0.042), undifferentiated histology (P = 0.047), and BRAF V600E mutation (P < 0.0001). Patients with HMCC showed worse clinical outcomes than those with low-methylated CRC in terms of RR (P = 0.017), PFS (P = 0.004), and OS (P = 0.019). In the multivariate analysis, peritoneal metastasis (P = 0.017), methylation status (P = 0.037), and BRAF V600E mutations (P = 0.0001) were independent factors for shorter PFS.

conclusionsGenome-wide DNA methylation status is an independent factor associated with PFS in patients with mCRC treated with first-line EGFR inhibitors.
