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
introductionThe ileocolic vein (ICV) is an important anatomical landmark during surgery for right colon cancer. However, surgeons sometimes encounter anatomical variations in the vascular anatomy. Robot-assisted surgery, featuring articulated instruments and advanced three-dimensional visualization, offers significant advantages in managing complex vascular variations. This is the first documented instance of a preoperatively diagnosed ICV anomaly that was successfully treated using robot-assisted laparoscopy. PRESENTATION OF CASE: A 68-year-old woman with a medical history of bronchial asthma and allergy to contrast media presented with right lower abdominal pain. Further evaluation revealed the presence of ascending colon cancer. Noncontrast abdominal computed tomography showed that the roots of the ileocolic vein and artery were anatomically separated. The ICV joined the accessory right colic vein (ARCV) and drained into the gastrocolic trunk of the Henle. The right colic artery coursed ventrally toward the trunk and ran parallel to the ARCV. The patient underwent robotic-assisted laparoscopic right hemicolectomy with D3 lymph node dissection. DISCUSSION: In rare cases where the ICV drains into the GCT, recognizing vascular anatomy preoperatively is crucial. While conventional laparoscopy is feasible, robot-assisted surgery enhances safety and precision through improved articulation and dexterity, making it advantageous in anatomically complex situations.
conclusionWe performed robot-assisted laparoscopic right hemicolectomy for ascending colon cancer with anatomical variations in the ICV draining directly into the gastrocolic trunk. The robot-assisted approach enabled safe and precise dissection despite the vascular anomaly owing to its articulated instruments and enhanced visualization.
