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

purposePancreatic cancer (PC) has one of the worst prognoses among all solid cancers. Hospital volume has been shown to be significantly associated with outcomes in patients with PC undergoing surgery. Nonetheless, the association between hospital volume and prognosis in patients with metastatic PC remains unclear. This study aimed to examine the association between hospital volume and prognosis in patients with metastatic PC using large-scale population-based cancer registry data.

methodsThis retrospective observational study was conducted using data from the Osaka Cancer Registry database. Data of patients with metastatic PC over 10 years (2009-2018) were obtained. Hospitals were categorized into high-volume hospitals (HVHs; ≥ 240 patients diagnosed with PC for 10 years), middle-volume hospitals (MVHs; 120-239 patients diagnosed with PC for 10 years), and low-volume hospitals (LVHs; < 120 patients diagnosed with PC for 10 years). Multivariate analysis was performed to identify factors associated with overall survival (OS).

resultsThe analysis included 8,929 patients with metastatic PC. Median OS was significantly more favorable in HVHs than in MVHs and LVHs. Multivariate analysis adjusted for hospital volume, age, primary tumor site, year of diagnosis, chemotherapy, and radiotherapy revealed that hospital volume was an independent factor associated with OS (HVHs vs. MVHs: hazard ratio [HR], 1.10; 95% confidence interval [CI], 1.03-1.16; P = 0.003, HVHs vs. LVHs: HR, 1.20; 95% CI, 1.13-1.27; P < 0.001).

conclusionHospital volume is an independent prognostic factor in patients with metastatic PC, suggesting an association between hospital volume and treatment outcomes.
