Imaging characteristics of central neurocytomas according to Ki-67 proliferation index.
Article in Frontiers in oncology, 2025. 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
Purpose: To evaluate the imaging characteristics of central neurocytoma (CN) with different Ki-67 indices and reveal its biological behavior. Materials and methods: Sixty-nine cases of intraventricular CN confirmed by histopathology were collected retrospectively. According to Ki-67 indices, they were divided into CNs with high Ki-67 (30 cases) and CNs with low Ki-67 (39 cases). Their clinical and imaging findings were compared and analyzed. Results: Compared to CNs with low Ki-67, CNs with high Ki-67 were larger (P < 0.001) and more solid (P = 0.019). Restricted diffusion (P = 0.020), CT hyperdensity (P < 0.001), abnormal vessels (P = 0.018), and marked MRI enhancement (P < 0.001) were more common in CNs with high Ki-67. Conclusion: Different Ki-67 indices could affect the imaging characteristics of CNs. Tumor size, radiologic solidity, abnormal vessels, and marked MRI enhancement suggested CNs with high Ki-67. Combining these imaging characteristics and Ki-67 indices offered meaningful insights into their clinical diagnosis and biological behavior.
