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
backgroundIntracorporeal delta-shaped Billroth I (B-I) anastomosis following minimally invasive distal gastrectomy (DG) is a simple and highly reproducible gastroduodenostomy procedure. This study aimed to identify the technical pitfalls of this procedure and assess their influence on one-year outcomes.
methodsThis was a retrospective study including patients who underwent delta-shaped B-I anastomosis following minimally invasive DG at our institution between 2008 and 2022. Delta-shaped B-I anastomosis was performed by adhering to five fundamental elements. Data were collected from our prospectively maintained database and analyzed retrospectively. Intra- and postoperative complications were reviewed, and video analysis was performed to identify technical errors associated with these complications. One-year outcomes, including nutritional status and endoscopic findings, were compared between patients with and without complications within 30 days after surgery.
resultsA total of 749 patients were included in this study. A total of 36 operating surgeons were involved. Intraoperative anastomotic complications occurred in 0.8% of patients, mainly due to technical issues during linear stapling. Postoperative anastomosis-related complications occurred in 2.1% of patients, with anastomotic leakage, stricture, and delayed gastric emptying rates of 0.9%, 0.3%, and 0.9%, respectively. Most complications were managed conservatively or endoscopically. No late-onset strictures were observed at postoperative year 1, and no significant differences in nutritional and endoscopic findings were observed between patients with and without complications.
conclusionWhen performed according to five fundamental technical principles, intracorporeal delta-shaped B-I anastomosis following minimally invasive DG proved to be a safe, reproducible procedure associated with favorable one-year outcomes.
