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

purposeTo evaluate the clinical characteristics and short-term outcomes of minimally invasive surgery (MIS) for right-sided colon cancer with superior mesenteric artery rotation (SMAR) when the SMA is found, intraoperatively, to run anterior to the superior mesenteric vein (SMV) in the ileocolic root area.

methodsThe subjects of this retrospective analysis were patients with right-sided colon cancer, who underwent MIS with D3 lymph node dissection between 2018 and 2024. We compared the clinical characteristics and short-term outcomes of MIS in patients with and those without SMAR. The findings of SMAR were defined on preoperative computed tomography as ct-SMAR.

resultsAmong the 523 patients included in this analysis, there were 513 (98.1%) without SMAR and 10 (1.9%) with SMAR. It was identified that 60.0% of the patients with SMAR had cecum cancer vs.25.1% of those without SMAR. The sensitivity and specificity of the findings of ct-SMAR were 80.0% and 97.5%, respectively. Both operative time (183 min vs. 231 min, p = 0.004) and blood loss (0 mL vs. 27 mL, p = 0.012) were significantly higher in the patients with SMAR.

conclusionThe vascular course in patients with SMAR differs from the usual pattern and this may increase the risk of unexpected vascular injury, potentially leading to intraoperative bleeding and prolonged operative time.
