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

objectivesThe association between hospital volume and outcome following high-risk low volume cancer surgery is well documented. However, this association is not well understood in cancer patients undergoing non-surgical therapies. We explored this association in a cohort of newly diagnosed patients with hepatocellular carcinoma (HCC).

methodsData from the 2000 through 2011 in Texas Cancer Registry were used to study adults with newly diagnosed HCC (17,231 patients from 322 hospitals). Hospital volume was stratified into low and high volume using Contal's outcome-based method. A multivariable Cox regression with shared frailty was used to evaluate the association between hospital volume and overall survival. The relationship between treatment modality and hospital volume was explored using mixed effects logistic regression.

resultsThe majority (61%) of HCC patients were seen in 21 high-volume hospitals. An annual hospital volume cutoff point of 24 patients was determined to stratify between high- and low-volume hospitals. Patients at high-volume hospitals presented more commonly with localized disease (56 vs. 50%, P<0.01) and were more likely to receive curative therapies including surgical resection, liver transplantation, or ablation (22 vs. 12%, P<0.01). High-volume hospitals were significantly associated with improved survival (HR=0.96, 95% CI=0.94-0.98). In multivariable analysis, hospital volume was associated with increased overall treatment utilization (OR=1.3, 95% CI=1.2-1.4).

conclusionsHospital volume is associated with improved overall survival, particularly in localized HCC. Improved survival may be mediated by increased utilization of treatments in high HCC volume hospitals.
