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

backgroundEsophageal cancer is a significant health burden in China, commonly treated by esophagectomy, a procedure with considerable risks. While higher hospital volume is associated with improved outcomes in Western countries, it remains unclear if this volume-outcome relationship persists in China, where many centers handle a relatively high caseload compared to Western standards. This study investigated the impact of hospital volume on perioperative morbidity and long-term survival outcomes following esophagectomy for esophageal cancer within the context of Chinese medical centers.

methodsThis study analyzed data from a prospective multicenter database (April 2015-December 2018) including 6775 patients with clinical stage cT1b-3N0-1M0 esophageal cancer undergoing radical esophagectomy across 19 Chinese centers. Centers were categorized based on procedural volume over 3.5 years: Group A (high-volume: ≥ 400 cases) and Group B (low-volume: < 400 cases). Perioperative complications and 5-year overall survival (OS) and disease-free survival (DFS) were compared. Propensity score matching (PSM) was employed to balance baseline characteristics between groups.

resultsAnalysis included 6,125 patients (4,633 Group A, 1,492 Group B) for survival outcomes. Group B demonstrated significantly higher rates of total complications (23% vs 19%, P < 0.001), including anastomotic leakage (5.9% vs 4.5%, P = 0.014), cardiovascular events (2.0% vs 0.9%, P < 0.001), and recurrent laryngeal nerve paralysis (12.1% vs 10.0%, P = 0.033), alongside longer mean operation times (P < 0.001). After PSM (1,492 matched pairs), Group A maintained superior 5-year OS (49% vs 45%, P < 0.05, HR: 1.12, 95%CI, 1.01-1.23) and 5-year DFS (45% vs 42%, P < 0.05, HR: 1.14, 95%CI, 1.03-1.25) compared to Group B.

conclusionsHospital volume significantly influenced esophagectomy outcomes in China, even among centers with relatively high caseloads. Treatment at high-volume centers was associated with lower postoperative morbidity and better long-term survival for patients with esophageal cancer.
