Outcomes of Reduced-Port Robotic Gastrectomy Compared With the Conventional Laparoscopy in Korea (KLASS-13).
Article in Journal of gastric cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeRadical gastrectomy with lymphadenectomy remains the standard treatment for gastric cancer. Minimally invasive gastrectomy, particularly the reduced-port robotic gastrectomy (REPROG), has gained attention because of its precision and reduced invasiveness. This study aimed to establish a nationwide REPROG database in Korea and to evaluate its clinical outcomes. MATERIALS AND
methodsAll patients who underwent REPROG between February 2014 and December 2023 were analyzed. A comprehensive analysis of these patients, including perioperative outcomes, was conducted. To compare outcomes, a control group was selected from the 2019 Korea Nationwide Gastrectomy Database, focusing on patients receiving multiport conventional laparoscopic gastrectomy (CLG). A 1:2 propensity score matching was performed based on patient, tumor, and surgical characteristics. Perioperative outcomes, including the length of hospital stay, were compared between the matched cohorts.
resultsA total of 1,071 patients who underwent REPROG were collected, of which 1,060 were included after exclusion and compared with CLG cases from a nationwide database. REPROG demonstrated a significant reduction in hospital stay, with a mean duration of 6.1 days compared with 7.8 days for the CLG (P<0.001). The incidence of major complications was similar between the 2 groups (1.9% vs. 2.4%, P=0.493). The conversion rate for REPROG was 0.19%. The annual number of patients receiving REPROG steadily increased, reaching 267 patients (24.9%) by 2023.
conclusionsPatients undergoing REPROG had a shorter hospital stay and a low conversion rate, indicating its potential as a treatment option for gastric cancer when performed by highly experienced surgeons.
