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

To evaluate the surgical and oncological outcomes of robotic surgery for pT4 colorectal cancer compared with laparoscopic and open approaches. This multicenter retrospective study included 494 patients undergoing curative resection for pT4 colorectal cancer (2016–2025). Patients were categorized into robotic (R; n = 31), laparoscopic (L; n = 379), and open (O; n = 74) groups. Short-term outcomes and disease-free survival (DFS) were assessed. To determine independent predictors of postoperative complications, we applied multivariable logistic regression models (Trial registration: UMIN000059581). The R group achieved the lowest median blood loss (20 vs. 25 vs. 186 mL; p < 0.001) and zero conversions, despite longer operative times (276 vs. 249 vs. 208 min; p = 0.001). Complication rates (Clavien-Dindo ≥ II) were comparable among the groups (22.6%, 23.5%, and 28.4%; p = 0.652). In multivariable analysis, surgical approach was not associated with postoperative complications (Robotic vs. Laparoscopic: OR 0.77, 95% CI 0.28–1.87; p = 0.581). Regarding oncological outcomes, 3-year DFS showed similar trends across the three groups (log-rank p = 0.71). Robotic surgery for pT4 colorectal cancer resulted in minimal blood loss and zero conversions. The procedure demonstrated perioperative safety and feasibility comparable to laparoscopic surgery. In oncology, 3-year DFS showed similar trends, although long-term confirmation is required. Trial registration number: UMIN000059581, date of registration: October 29, 2025, retrospectively registered.
