Augmented Reality Navigation-Assisted Laparoscopic Hepatectomy: A Retrospective Comparison of Anatomical and Non-anatomical Resection.
Article in Clinical Medicine Insights. Oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Augmented reality navigation (ARN) has been increasingly applied in laparoscopic liver surgery to improve anatomical orientation and surgical precision. However, its clinical value compared with conventional anatomical liver resection (ALR) and non-anatomical liver resection (NALR) remains unclear. Method: This retrospective single-center study included 96 patients with hepatocellular carcinoma who underwent laparoscopic hepatectomy from January 2019 to December 2021. Patients were divided into three groups: ARN-assisted laparoscopic nonanatomic hepatectomy (Group A, n=28), laparoscopic anatomical hepatectomy without navigation (Group B, n=35), and laparoscopic nonanatomic hepatectomy without navigation (Group C, n=33). Baseline demographic, clinical, tumor, and segmental distributions were comparable among groups. Postoperative outcomes, postoperative complications, and 36-month follow-up data were analyzed. Result: Preoperative characteristics did not significantly differ among the three groups. Operative time was significantly shorter in Group A than in Group B ( Conclusion: In this cohort, ARN-assisted laparoscopic nonanatomic hepatectomy was associated with reduced operative time and blood loss and demonstrated short-term oncological outcomes similar to anatomical hepatectomy. These findings suggest that ARN may enhance the effectiveness of non-anatomical hepatectomy; however, confirmation in larger prospective studies is required.
