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

purposeThis study compared short- and mid-term outcomes between robot-assisted surgery (Robot) and laparoscopic surgery (Lap) for splenic flexure colon cancer.

methodsWe analyzed patients who underwent minimally invasive surgery for splenic flexure colon cancer between April 2018 and November 2024. The patients were divided into the Robot and Lap groups. The perioperative outcomes, postoperative complications, and survival data were also evaluated. The overall survival (OS) and disease-free survival (DFS) were estimated using the Kaplan–Meier method.

resultsIn total, 32 and 20 patients underwent Robot and Lap, respectively. The Robot group had a significantly higher rate of lymph node dissection with division of the left branch of the middle colic artery (43.8% vs. 15.0%, p = 0.038), less intraoperative blood loss (0 mL vs. 28 mL, p = 0.008), and more frequent intracorporeal anastomosis (34.4% vs. 0.0%, p = 0.004). The postoperative complications and pathological outcomes were similar. The 3-year DFS rates were comparable (Robot: 80.7% vs. Lap: 91.7%, p = 0.629).

conclusionRobot-assisted surgery for splenic flexure colon cancer resulted in reduced blood loss and similar short- and mid-term outcomes compared with laparoscopic surgery. Robotic systems may offer enhanced precision for complex procedures and thereby improve the safety and technical performance.
