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
backgroundThe perichondrium-a natural fibrous membrane encasing cartilage-plays a pivotal role in nutrient delivery and matrix regulation; however, it is often overlooked in engineered constructs. This study aimed to fabricate a perichondrium-mimicking three-dimensional (3D) bioprinted auricular cartilage construct utilizing a hybrid bioink and to assess the effects of adipose-derived stem cell (ADSC) outer layers on cartilage matrix formation, vascularization, and construct stability.
methodsChondrocyte spheroids and ADSCs were isolated from New Zealand white rabbits and embedded in bioinks composed of either alginate alone or alginate/GelMA composites. A dual-mode printing strategy facilitated the fabrication of constructs with 3 and 10 layers. ADSCs were printed as outer "perichondrium-mimicking" layers in designated groups (G2, G4, and G6). Constructs were implanted subcutaneously in nude mice for 6 weeks. Histological analyses, immunohistochemical assessments (CD31), and image-based quantitative analyses were conducted.
resultsThe inclusion of ADSC layers significantly enhanced cartilage matrix synthesis and decreased calcification, particularly in constructs containing GelMA. Group G4 exhibited the highest levels of glycosaminoglycan and collagen content, as well as the lowest calcium deposition. Ten-layer constructs (G6) preserved structural integrity and supported neovascularization; however, the final cartilage thickness did not proportionally scale with the initial print height.
conclusionThe incorporation of ADSC-laden perichondrium-mimicking layers in conjunction with a hybrid alginate/GelMA bioink synergistically enhances cartilage formation, matrix quality, and vascular integration in large constructs. This biomimetic approach is a promising platform for developing clinically relevant cartilage grafts for auricular reconstruction and other cartilage repair applications.
