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

backgroundSince 2013, The Japan Esophageal Society has been certifying "Authorized Institute for Board Certified Esophageal Surgeon (AIBCES)" to contribute to improving national medical care by enhancing the professional knowledge and skills of esophageal surgeons. However, the appropriateness on this certification system has not yet been verified. Our aim was to assess the appropriateness of the institute certification system for esophageal surgeries used by the medical society.

methodsUsing data from the National Database of Hospital-based Cancer Registries, we analyzed the 5-year overall survival rates among 2135 patients with thoracic esophageal cancer who underwent an esophagectomy at 53 AIBCES or 141 non-AIBCES.

resultsThere were 1343 (63%) patients who underwent surgery at an AIBCES and 792 (37%) who underwent surgery at a non-AIBCES. Registered patients were followed up for a median of 53 (range 1-88) months. Over the followed-up period examined, 670 (50%) patients treated at an AIBCES died and 455 (57%) treated at a non-AIBCES died. Comparison of the Kaplan-Meier survival curves indicated that patients with cStage II or cStage III disease treated at an AIBCES had significantly better 5-year survival rates than those treated at a non-AIBCES (55.4% vs. 44.9% and 38.0% vs. 30.3%, respectively). Univariate and multivariate analyses stratified based on stages and adjuvant therapies revealed that institute certification (AIBCES vs. non-AIBCES) is a significant independent factor for 5-year survival.

conclusionsThe institute certification system used by the Japan Esophageal Society may be appropriate, as indicated by improved 5-year survival outcomes. The institute certification system has the potential to contribute to a more appropriate medical delivery system in the future.
