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
The glenoid labrum is a fibrocartilaginous structure essential for shoulder stability, yet its regeneration remains an unmet clinical challenge. Current surgical approaches restore initial joint stability but frequently fail to reestablish native biomechanics, leading to recurrence and early degenerative changes. In this study, we investigated the feasibility of fabricating a patient-specific, anatomically scaled glenoid labrum scaffold using digital modeling based on magnetic resonance imaging and 3D cryo(bio)printing of a gelatin methacryloyl (GelMA) hydrogel. Printing was performed in a temperature-controlled platform (22.5 °C, 15 °C, and -20 °C) to evaluate the influence of thermal conditions on structural fidelity and biological performance. Quantitative analyses showed that cryogenic deposition markedly improved printing precision, reducing filament spreading and enhancing geometric accuracy in both sharp-angle and grid-pattern evaluations. Biological assays indicated high viability of human mesenchymal stem cells under all temperature conditions, validating the cytocompatibility of the methodology. Morphological assessment by structured-light 3D scanning demonstrated that bioprinted patient-specific scaffold at -20 °C achieved the highest correspondence to the digital reference model. Overall, the integration of anatomical modeling with cryo(bio)printing proved to be an effective approach for producing anatomically faithful, patient-tailored scaffolds. This study presents the first demonstration of human glenoid labrum bioprinting and establishes a foundation for future translational research in fibrocartilaginous tissue regeneration.
