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.
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
backgroundWhile endoscopic treatments such as endoscopic submucosal dissection have been developed for superficial esophageal cancer, additional treatment is often required when resection is incomplete or when pathology reveals submucosal invasion. Additional treatment options include esophagectomy or chemoradiation therapy (CRT), and no clear consensus exists on which approach is superior. This study aims to evaluate the preferred adjuvant treatment following non-curative endoscopic resection.
methodsThis retrospective study included 113 patients who underwent additional treatment after non-curative endoscopic resection between August 2007 and December 2020. Of these, 31 patients underwent esophagectomy, and 82 received CRT. Propensity score matching identified 29 patients from each group with comparable baseline characteristics, and overall survival (OS), recurrence-free survival (RFS), and time to recurrence (TTR) were analyzed and compared between the groups.
resultsIn the entire cohort, there were no significant differences between the esophagectomy and CRT groups in terms of age, sex, pathologic depth, tumor localization, tumor size, lymphatic invasion, vascular invasion, and the vertical margin status. However, there was a significant difference in the horizontal margin status. In the matched cohort, there was no significant difference in OS between the two groups (p = 0.9), but the surgery group demonstrated a significantly better RFS and TTR than the CRT group (p = 0.048, p = 0.004).
conclusionFor patients requiring additional treatment after non-curative endoscopic resection of superficial esophageal cancer, esophagectomy appears to offer better RFS and TTR compared with CRT and may represent the more appropriate treatment option.
