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

backgroundThis study evaluates the influence of facility case-volume on nasopharyngeal carcinoma (NPC) treatments and overall survival (OS).

methodsThe 2004-2015 National Cancer Database was queried for patients with NPC receiving definitive treatment.

resultsA total of 8260 patients (5-year OS: 63.4%) were included. The 1114 unique facilities were categorized into 854 low-volume (treating 1-8 patients), 200 intermediate-volume (treating 9-23 patients), and 60 high-volume (treating 24-187 patients) facilities. Kaplan-Meier log-rank analysis demonstrated significantly improved OS with high-volume facilities (p < 0.001). On cox proportional-hazard multivariate regression after adjusting for age, sex, income, insurance, comorbidity index, histology, AJCC clinical stage, and treatment type, high-volume facilities were associated with lower mortality risk than low-volume (HR = 0.865, p = 0.019) and intermediate-volume facilities (HR = 0.916, p = 0.004). Propensity score matching analysis confirmed this association (p < 0.001).

conclusionHigher facility volume was an independent predictor of improved OS in NPC, suggesting a possible survival benefit of referrals to high-volume medical centers.
