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

purposeThe optimal approach for minimally invasive (MIS) right colectomy remains under debate. This study aimed to describe surgical trends in the treatment of nonmetastatic right colon cancer and to identify predictors of short-term surgical outcomes.

methodsA retrospective multicenter cohort study of Minimally-invasivE surgery for oncologic Right ColectomY (MERCY) was conducted on patients who underwent laparoscopic or robotic right colectomy between 2014 and 2020. Classification tree approach was used to describe the extracorporeal (EA) or intracorporeal (IA) anastomosis choice. Mixed-model regressions were used to identify patient- and surgery-related factors predictive of postoperative outcomes. A questionnaire was used to evaluate the surgeons' perspectives.

resultsThe MERCY database comprised 1870 patients; 87.2% underwent laparoscopy, and 68.1% received an EA. A clear surgical trend was noted, with an increasing rate of IA and robotic procedures after 2017. EA represented 41% of anastomoses in centers equipped with a robotic surgical system. Mixed-model regressions (on 1088 patients) showed that age, sex, BMI, comorbidity, robotics, IA, and conversion to open surgery were predictors of surgical outcomes. In particular, IA was a predictor of a shorter time to regular diet and fewer surgical site infections. Based on the questionnaire, IA was the preferred over EA by 72% of surgeons.

conclusionMIS continues to evolve, with an increasing number of IA being performed in the recent years and when using a robotic surgical system. Understanding the role of predictors of surgical outcomes may help surgeons personalize decision-making among the different MIS options to manage right colon cancer.
