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

Purpose: Surgical resection of remnant gastric cancer (RGC) is technically challenging and difficult. Minimally invasive surgery (MIS) has been adopted for various procedures, but reports of MIS for RGC remain limited. Herein, we report the surgical techniques and short-term outcomes of MIS for RGC. Methods: We conducted a retrospective cohort study involving 61 consecutive RGC patients who underwent open or minimally invasive (laparoscopic or robotic) total gastrectomy for potentially curable RGC at our institution (January 1999-August 2025). A propensity score-matched cohort was used for an exploratory evaluation of the safety and efficacy of MIS for RGC, focusing on feasibility rather than superiority over open surgery. Results: Of these 61 patients, 53 underwent open surgery and eight underwent MIS gastrectomy for RGC. The median age was 70 years. The cohort comprised 53 men and eight women. The initial procedure was open surgery in 58 patients and MIS in three patients. Propensity score matching showed significantly reduced intraoperative blood loss in the MIS group compared with the open surgery group (39 mL vs. 576 mL, Conclusion: MIS, including robotic gastrectomy, is feasible and safe for RGC, with potential perioperative benefits requiring multicenter validation.
