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

backgroundRobotic gastrectomy (RG) has emerged as a promising approach for gastric cancer (GC) treatment, offering advantages such as enhanced dexterity, improved visualization, and increased precision. However, its widespread adoption remains limited due to technical complexity, high costs, limited applications, and insufficient evidence.

methodsWe conducted a single-center, prospective study to evaluate the safety and feasibility of RG, including robotic total gastrectomy (RTG), robotic proximal gastrectomy (RPG), and robotic distal gastrectomy (RDG) with D1+ or D2 lymphadenectomy, in clinical stage I/II GC. The primary endpoint was the incidence of intraoperative and postoperative complications, while the secondary endpoints included surgical outcomes and long-term prognosis.

resultsSeven patients were enrolled. No intraoperative complications or conversions to open surgery occurred. The primary endpoint was met, with no major postoperative complications. RTG had a longer operative time and more lymph nodes dissected than RDG and RPG. The median postoperative hospital stay was 10 days. Recurrence was observed in two cases, one of which achieved long-term survival without chemotherapy.

conclusionOur findings demonstrate the safety and feasibility of RG for early and advanced GC. Further multicenter studies with larger cohorts are needed to establish its oncological benefits and cost-effectiveness, facilitating broader clinical adoption.
