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
We present a robotic approach to tumor-specific mesocolic excision with D3 lymph node dissection for descending colon cancer. This technique is based on three established principles: the radical en bloc lymphadenectomy of Japanese D3 lymph node dissection, the fascial plane-oriented sharp dissection of Western complete mesocolic excision, and the tumor-adapted rationale of tumor-specific partial mesorectal excision in rectal cancer. Key procedural elements include dissection along the embryological mesocolic plane, standardized 10-cm proximal and distal margins, en bloc lymphadenectomy of stations 231 (paracolic), 232 (intermediate), and 253 (apical), selective ligation of tumor-feeding arteries such as the left colic artery and sigmoid arteries, and preservation of the inferior mesenteric artery trunk to maintain perfusion to the distal bowel. Robotic assistance enables meticulous vascular control and precise mesocolic plane preservation. Between May 2023 and May 2025, 20 patients underwent this procedure without conversions to open surgery or intraoperative complications. The median age was 57 years (IQR 45-69), and median BMI was 22.6 kg/m
