Precision distance control in ultrasound-guided coaxial needle biopsy for small liver cancer: improving safety and diagnostic accuracy yield.
Article in Frontiers in oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Objective: The diagnostic yield of percutaneous biopsy for small liver cancer is affected by lesion size and location. This study utilizes small components with a coaxial cannula to enables precise control over specimen length, aiming to evaluate the safety and clinical applicability of ultrasound-guided coaxial needle biopsy. Methods: In the coaxial group, the biopsy gun's position relative to the coaxial cannula was adjusted, and small components were used to control specimen length. Thrombin (1-2 KU) was injected along the needle tract post-procedure. In the non-coaxial group, multiple needle insertions targeted the lesion edge. Complications and pathology results were recorded to assess clinical efficacy. Results: A retrospective analysis of 744 patients from Jiangsu Provincial Cancer Hospital showed a higher pathological detection rate in the coaxial group (95.6%, 198/207) than in the non-coaxial group (89%, 478/537). Intraoperative bleeding was more easily detected in the coaxial group, allowing timely intervention. Pain was reported in 15% (31/207) versus 30% (161/537), respectively. No needle tract implantation occurred in either group. Conclusion: Ultrasound-guided coaxial needle biopsy for small liver cancer (≤2 cm) significantly improves diagnostic accuracy (P = 0.005), reduces procedure complexity and complications, and enhances patient outcomes, demonstrating excellent safety and clinical value.
