Comparative Outcomes of Open, Laparoscopic, and Robotic Right Colectomy for Colon Cancer: Postoperative Recovery, Surgical Quality, and 3-Year Survival-A Monocentric Retrospective Study.

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
BACKGROUND/
objectivesMinimally invasive approaches are increasingly used in right colectomy for colon cancer; however, comparative data, including open, laparoscopic, and robotic techniques, remain limited, particularly regarding postoperative recovery and oncological outcomes.
methodsThis retrospective monocentric study included 89 patients undergoing elective right colectomy for colon cancer between July 2018 and December 2022. Of these, 30 patients underwent open, 29 laparoscopic, and 30 robotic-assisted surgery. The primary endpoint was postoperative recovery, defined as the time to first bowel movement. Secondary endpoints included length of hospital stay, complete mesocolic excision (CME) quality, lymph node yield, C-reactive protein (CRP) on postoperative day one, operative time, overall survival (OS), and disease-free survival (DFS). Multivariable regression analyses were performed adjusting for age, sex, BMI, ASA score, UICC stage, and tumor size.
resultsTime to first bowel movement was shorter after minimally invasive surgery (median robotic 3.5, laparoscopic 4 vs. open 5 days) and length of hospital stay was numerically shorter (mean 9.1 vs. 10.1 days). CME quality and lymph node yield did not differ significantly between the approaches, and postoperative day-one CRP was numerically lower after robotic (median 4.9 mg/dL) and laparoscopic (5.1 mg/dL) than after open surgery (7.1 mg/dL), without reaching statistical significance after adjustment. Operative time was significantly longer with minimally invasive surgery (robotic +50 min; laparoscopic +43 min vs. open; both
conclusionsNo statistically significant difference in surgical quality between the approaches was detected, while operative time was significantly longer after minimally invasive surgery. No statistically significant independent association between the surgical approach and postoperative recovery or three-year oncological outcomes was detected; given the limited precision of the estimates, clinically important differences cannot be excluded.
