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 compared the outcome between patients who had an open and those who had a hybrid esophagectomy for T1 or T3 esophageal adenocarcinoma (eAC). No clear data are available concerning this question based on T-category.

methodsTwo groups of patients with esophagectomy and high intrathoracic esophagogastrostomy for eAC were analyzed: hybrid (laparoscopy + right thoracotomy) (n = 835) and open (laparotomy + right thoracotomy) (n = 188). Outcome criteria were 30- and 90-day mortality, R0-resection rate (R0), number of resected lymph nodes (rLNs), and 5-year survival rate (5y-SR). For each type of surgery, three patient groups were analyzed: pT1-carcinoma (group-1), cT3Nx and neoadjuvant chemoradiation (group-2), and pT3N0-3 without neoadjuvant therapy (group-3). The comparison was based on a propensity score matching in relation of 1:2 for open versus hybrid.

resultsIn group-1 (38 open vs 76 hybrid) R0-resection (100%), 30-day mortality (0%), 90-day mortality (2.6% vs 0%), and rLNs (median 29.5 vs 28.5) were not significantly different. The pN0-rate was 76% in the open and 92% in the hybrid group (p = 0.036). Accordingly, the 5y-SR was 69% and 87% (p = 0.016), but the prognosis of the subgroups pT1pN0 or pT1pN+ was not significantly different between open or hybrid. In group-2 (68 open vs 135 hybrid) R0-resection (97%), 30-day (0% vs 0.7%) and 90-day (4%) mortality, rLNs (28.5 vs 26), and 5y-SR (36% vs 41%) were not significantly different. In group-3 (37 open vs 75 hybrid) R0, postoperative mortality, rLNs, and 5y-SR were not significantly different.

conclusionIn a propensity score-matched comparison of patients with an open or hybrid esophagectomy for esophageal adenocarcinoma the quality of oncologic resection, postoperative mortality and prognosis are not different.
