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
Accurate quantitative assessment of temporal bone microanatomy is essential for otologic research and surgical planning. However, existing measurement approaches, including manual tools, ex vivo microscopy, and high-resolution computed tomography, are limited by contact requirements, indirect measurement, insufficient spatial resolution, or the inability to provide efficient quantitative feedback under microscopic visualization. To address these limitations, this study developed an in situ, non-contact three-dimensional (3D) microscopic measurement system for temporal bone anatomy based on stereo imaging. The system integrates microscopic stereo calibration, deep learning-based disparity estimation, 3D reconstruction, and an interactive measurement workflow. Reconstruction accuracy was evaluated using a high-precision scanned LEGO model, while measurement accuracy was validated using a custom-designed 3D-printed module with known geometric dimensions. The feasibility of the system was further demonstrated through measurements of representative anatomical structures in four temporal bones from two fresh-frozen cadaver heads. The results showed that the root mean square error of 3D reconstruction was 0.05-0.13 mm. For geometric measurements, the average error was below 1.7%, with a maximum error below 4.0% across multiple metrics. The system enabled in situ, non-contact measurement of various anatomical parameters under microscopic conditions. These findings indicate that the proposed system provides accurate and reliable quantitative 3D measurement of temporal bone microstructures. As a technical prototype, it provides a practical tool for anatomical research and supports future development toward intraoperative, non-contact, in situ quantitative assessment in otomicrosurgery.
