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

purposeThere are limited reports on the safety of robotic surgery compared to laparoscopic surgery for colon cancer. In this study, we examined the impact of robotic surgery on the short-term outcomes of colon cancer using a multicenter database.

methodsWe retrospectively reviewed 4084 consecutive patients with colon cancer who underwent minimally invasive surgery between April 2016 and December 2025. Patients were classified into two groups according to the surgical approach: robotic surgery (R group, n = 438) and laparoscopic surgery (L group, n = 3646). Propensity score matching was applied to minimize selection bias and balance the covariates. Finally, 438 patients in each group were matched for analysis. The clinicopathological features were compared between the groups.

resultsAfter matching, blood loss was lower (10 mL vs. 15 mL, p = 0.027), the conversion rate was lower (0.4% vs. 5.9%, p < 0.001), postoperative complications were fewer (7.5% vs. 15.3%, p < 0.001), and hospital stay was shorter (10 days vs. 12 days, p < 0.001) in the R group. The operation time was similar between the groups (p = 0.905).

conclusionsRobotic surgery for colon cancer may help reduce the need for open conversion and the incidence of postoperative complications.
