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

The association between regorafenib dosage in the treatment of metastatic colorectal cancer (mCRC) and efficacy is currently not well established. It was previously reported that the regorafenib dose as prescribed is associated with efficacy, but doses in actual clinical settings have not been analyzed. We retrospectively analyzed patients with mCRC who had received regorafenib as third-line or later chemotherapy between May 2013 and June 2018. Patients who were not treated in the Pharmaceutical Outpatient Clinic for compliance assessment were excluded. Overall survival was calculated using the Kaplan-Meier method. Prognostic factors, including baseline demographics and adverse events, were evaluated using Cox proportional hazard models. A total of 176 patients were enrolled. By multivariate analysis, total dose until the second cycle < 3180 mg (HR = 1.71, 95% CI, 1.20-2.44,
