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 phenotype maintenance of diced cartilage is a very important factor to reduce cartilage absorption rate in augmentation rhinoplasty. A novel method which combined diced cartilage with chondrocyte spheroids in gelatin methacrylate (GelMA) hydrogel may have potentially good performance in phenotype maintenance, and is worth exploring.
methodsThe complex grafts formed by loading diced cartilage with chondrocyte spheroids into GelMA hydrogel were used as the experimental group, and the grafts formed of diced cartilage in GelMA were used as the control group. The two groups of grafts were implanted subcutaneously in nude mice. After 1 month and 3 months, the grafts were taken for general observation and histological analysis. The diameter changes of cartilage, the nuclei loss of chondrocyte, and glycosaminoglycan secretion were analyzed.
resultsChondrocyte spheroids with obvious proliferation can be seen in the experimental group. Some diced cartilages had become a whole through the interconnection of chondrocyte spheroids. In addition, the diameter of the chondrocyte spheroids-diced cartilage complex in the experimental group increased significantly, and its nuclei loss rate was less than 1/2 of that in the control group. The maintenance of proteoglycans in diced cartilages in the experimental group was significantly better than that in the control group.
conclusionThe combination of diced cartilage with chondrocyte spheroids in GelMA hydrogel can significantly reduce the absorption of cartilage extracellular matrix, enhance phenotype maintenance during subcutaneous ectopic implantation, and can produce inter-chondral connections.
