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

backgroundThe purpose of this study was to characterize disparities among centers performing major surgery for esophageal or gastric cancer stratified by case volume.

methodsThe National Cancer Data Base (NCDB) was queried for cases of esophagectomy or total gastrectomy. Centers were compared based on number of cases during 2004-2013: low volume [1-99], middle [100-200], and high [>200].

resultsFor esophagectomy, 17,547 patients were included; 73.5% were treated in low volume centers, 14.6% in middle, and 11.9% in high. For gastrectomy, 20,059 patients were included, with 87.5%, 8.3%, and 4.3%, respectively. Patients treated at low volume centers were more likely to be of racial/ethnic minorities, uninsured, and have lower socioeconomic status. Overall survival (OS) was superior for patients treated at high volume centers. On multivariable analysis for either procedure, a higher number of disparate factors was identified in the low and middle volume centers compared to the high volume centers, which were associated with poorer OS.

conclusionsThis study identified higher numbers of disparate patient factors associated with low/middle volume centers compared to high volume centers, which were associated with worse OS, and further makes the case for performance of esophagectomy and total gastrectomy at high volume centers.
