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

backgroundThere are numerous techniques for right-sided colonic resections with primary ileocolic anastomosis. This study investigated the impact of various access routes and different anastomotic techniques on short- and long-term outcomes.

methodsA systematic literature search was performed in CENTRAL (Cochrane Central Register of Controlled Trials), PubMed, and Web of Science (last search December 15, 2025). All randomized clinical trials (RCTs) investigating surgical techniques for right-sided colonic resections (i.e., ileocecal resection, right hemicolectomy) were reviewed. A meta-analysis (random-effects model) was conducted. Risk of bias (Cochrane 2.0) and certainty of evidence (GRADE) were assessed.

resultsThirty-three RCTs with 3787 patients were included. Twelve RCTs (1552 patients) compared open with laparoscopic surgery. Open surgery may result in shorter operation time (MD - 38.75 min, 95% CI: - 60.24 to - 17.26, p < 0.01, I

conclusionsThis comprehensive systematic review provides level 1a evidence on access routes and anastomotic techniques for right-sided colonic resections. The evidence supports a laparoscopic approach with an intracorporeal anastomosis. However, the evidence does not favor a particular anastomotic technique. REGISTRATION: CRD42024543620 (PROSPERO).
