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

backgroundA major concern of complete mesocolic excision (CME) for right-sided colon cancer is whether it can be performed safely in obese patients. The aim of this study is to perform a contemporary evaluation of the perioperative safety and oncological outcomes of robotic CME for right-sided colon cancer in obese versus non-obese patients.

methodsThis was a single-institution retrospective cohort study of patients who underwent robotic CME for right-sided colon cancer between 2015 and 2023. Patients were divided into obese (BMI ≥ 30 kg/m

resultsOf 211 patients, 80 (37.9%) were obese. Complication rates did not differ significantly between obese and non-obese groups (any grade: 18.8% vs 12.2%, P = 0.24; grade III: 3.8% vs 1.5%, P = 0.30). No vascular injuries occurred in either group. Conversion rates (5.0% vs 0.8%, P = 0.05) and length of stay were similar. Obese patients had longer operative times (289.5 vs 247 min, P = 0.003) and greater blood loss (50 vs 30 mL, P = 0.025). No cases had positive circumferential resection margins. Lymph node harvest (34.5 vs 34 nodes, P = 0.85) and margin status were comparable. During median follow-up of 2.6 years, 3-year RFS was similar between groups (89.1% vs 86.7%, P = 0.63), with no significant differences in OS (100% vs 95.6%, P = 0.13).

conclusionsObesity was associated with longer operative times and increased blood loss but not with higher complication rates or worse survival outcomes. Robotic CME appears technically and oncologically feasible for both obese and non-obese patients with right-sided colon cancer.
