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

Laparoscopic total gastrectomy (LTG) is a highly technical surgery that can lead to postoperative complications. Whether the recently introduced robotic surgery overcomes the drawbacks of laparoscopic surgery in total gastrectomy remains controversial. Therefore, we aimed to elucidate the potential benefits of robotic total gastrectomy (RTG) and compare the short-term outcomes of RTG and LTG. We retrospectively analyzed 56 patients with primary gastric or esophagogastric junction cancer who underwent RTG or LTG between June 2017 and July 2021. The groups were compared in terms of operative outcomes and postoperative complications. Potential risk factors associated with postoperative complications were assessed by performing multivariable analysis using logistic regression models via the exact method. Operation time was significantly longer, and postoperative hospital stay was significantly shorter in the robotic group (550 vs. 466 min, P < 0.001; 13 vs. 18 days, P = 0.013, respectively). The incidence of overall postoperative complications of Clavien-Dindo grade ≥ II was 18.5% and 24.1% in the RTG and LTG groups, respectively. Pancreatic fistulas were not observed, but other local complications were observed in 0% and 17.2% of the RTG and LTG groups, respectively (P = 0.052). In the multivariable analysis, the independent risk factors for local complications were laparoscopic surgery (odds ratio [95% confidence interval] 8.542 [1.065-∞], P = 0.045) and esophagogastric junction cancer (16.646 [2.559-∞], P = 0.005). Compared with LTG, RTG was associated with fewer local complications (mainly anastomotic leakage), especially in cases of esophagogastric junction cancer with high anastomotic sites.
