Short-Term Surgical Outcomes of Robotic Gastrectomy Compared to Open Gastrectomy for Patients with Gastric Cancer: a Randomized Trial.
Trial report in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02292914 (Prospective Analysis of Robot-Assisted Surgery), which is not on this map. Cited by 11 papers, 3 of them syntheses that pooled 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.
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.

Abstract
backgroundRobotic gastrectomy (RG) has been shown to be a safe and feasible method in gastric cancer (GC) treatment. However, most studies are in Eastern cohorts and there is great interest in knowing whether the method can be used routinely, especially in the West.
objectivesThe aim of this study was to compare the short-term surgical outcomes of D2-gastrectomy by RG versus open gastrectomy (OG).
methodsSingle-institution, open-label, non-inferiority, randomized clinical trial performed between 2015 and 2020. GC patients were randomized (1:1 allocation) to surgical treatment by RG or OG. Da Vinci Si platform was used. INCLUSION CRITERIA: gastric adenocarcinoma, stage cT2-4 cN0-1, potentially curative surgery, age 18-80 years, and ECOG performance status 0-1. EXCLUSION CRITERIA: emergency surgery and previous gastric or major abdominal surgery. Primary endpoint was short-term surgical outcomes. The study is registered at clinicaltrials.gov (NCT02292914).
resultsOf 65 randomized patients, 5 were excluded (3 palliatives, 1 obstruction and emergency surgery, and 1 for material shortage). Consequently, 31 and 29 patients were included for final analysis in the OG and RG groups, respectively. No differences were observed between groups regarding age, sex, BMI, comorbidities, ASA, and frequency of total gastrectomy. RG had similar mean number of harvested lymph nodes (p = 0.805), longer surgical time (p < 0.001), and less bleeding (p < 0.001) compared to OG. Postoperative complications, length of hospital stay, and readmissions in 30 days were equivalent between OG and RG.
conclusionsRG reduces operative bleeding by more than 50%. The short-term outcomes were non-inferior to OG, although surgical time was longer in RG.
