Trial reportSurgical endoscopy2021
A randomized controlled trial of single-port versus multi-port laparoscopic distal gastrectomy for gastric cancer.
Trial report in Surgical endoscopy, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 25 papers, 1 of them a synthesis 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThis prospective randomized trial compared the invasiveness of laparoscopic gastrectomy using a single-port approach with that of a conventional multi-port approach in the treatment of gastric cancer. The benefit of single-port laparoscopic gastrectomy (SLG) over multi-port laparoscopic gastrectomy (MLG) has yet to be confirmed in a well-designed study.
methodsOne hundred and one patients who were scheduled to undergo laparoscopic distal gastrectomy for histologically confirmed clinical stage I gastric cancer between April 2016 and September 2018 were randomly allocated to SLG (n = 50) or MLG (n = 51). The primary endpoints were the postoperative visual analog scale pain scores. Secondary endpoints were frequency of use of analgesia, short-term outcomes, such as operating time, intraoperative blood loss, inflammatory reactions, postoperative morbidity, and 90-day mortality.
resultsThe postoperative pain score was significantly lower in the SLG group than in the MLG group (p < 0.001) on the operative day and the postoperative day 1-7. Analgesics were administered significantly less often in the SLG group than in the MLG group (1 vs. 3 days, p = 0.0078) and the duration of use of analgesics was significantly shorter in the SLG group (2 vs. 3 days, p = 0.0171). The operating time was significantly shorter in the SLG group than in the MLG group (169 vs. 182 min, p = 0.0399). Other surgical outcomes were comparable between the study groups.
conclusionsSLG was shown to be safe and feasible in the treatment of gastric cancer with better short-term results in terms of less severe pain and may be suitable for treatment of cStage I gastric cancer. CLINICAL
