Study on specific proteins involved in articular cartilage regeneration activity induced by decalcified bone transplantation.

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
backgroundThrough a comprehensive analysis of the joint synovial fluid produced in the process of rabbit articular cartilage regeneration, the role and characteristics of knee synovial fluid in the process of decalcified bone transplantation-induced articular cartilage regeneration were explored.
methodsTwenty New Zealand white rabbits (approximately 2.5 kg in weight) were selected, and bilateral distal femoral bones from two randomly selected rabbits were extracted. After decalcification, the bones were cut into 2 mm × 4 cm long decalcified bone strips. Meanwhile, the other 18 rabbits were randomly divided into three groups: the test group (8 rabbits), the positive control group (6 rabbits), and the blank group (4 rabbits). In the test group, the decalcified bone joint was transplanted into the rabbits at the articular cartilage defect; in the positive control group, the articular cartilage defect of the rabbits were treated and put aside; in the blank group, no rabbits were treated. On the day of transplantation, and on the 4th, 8th, 12th, and 16th weeks after transplantation, the joint synovial fluid of each group was taken for two-dimensional polyacrylamide gel electrophoresis (2D-PAGE), matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF-MS) analysis, and related database verification and identification, and compared with the positive control group and the blank group.
resultsUsing 2D-PAGE to separate various proteins in the synovial fluid of the rabbit knee joints, it was found that there were differential protein spots in the test group compared with the blank group and the positive control group. After conducting a comparative search and query in the UniProt database, through comprehensive analysis, it was finally found that three proteins with molecular weights of 23,429.4, 57,431.4, and 26,071.1 that may be related to the regeneration of articular cartilage appeared in the test group.
conclusionsIn the process of inducing the regeneration of articular cartilage using decalcified bone transplantation, knee joint synovial fluid produced specific proteins, which may play an important role in the regeneration of articular cartilage. These findings may offer novel ideas in laying a foundation for the in-depth study of articular cartilage regeneration.
