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
Introduction: To repair cartilage defect as well as the calcified cartilage layer (CCL) and bone tissue, there is need to fabricate a three-phase complex that mimics the natural cartilage tissue. Materials and methods: SF/Col-Ⅱ/HA scaffolds were constructed by low-temperature 3D printing, and to prepare a three-phase complex. The microstructure were showed using a SEM image analysis program. To observe collagen and glycosaminoglycan expression and analyze morphometric parameters, HE staining was performed to reveal new cartilage. Immunohistochemical were performed to investigate the collagen content and defect repair status in the new cartilage group in vitro and vivo. Results: Physical and biochemical properties and biocompatibility of three-phase complex met the requirements of constructing tissue-engineered cartilage. The OD values increased gradually at different time points. With increasing culture time, the OD values showed an upward trend. The HE and immunohistochemical staining results showed that new cartilage had formed at the defect and new cartilage formation occurred during in vivo repair. Conclusion: 3DP-anchored three-phase complexes have good physical and biochemical properties and biocompatibility and thus represent an alternative cartilage tissue engineering material.
