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
Background/Objective: This study evaluated the impact of adipose tissue-derived mesenchymal stromal cells (ADSCs) on bone-tendon healing in rabbit anterior cruciate ligament (ACL) reconstruction. Methods: Nineteen mature male Japanese White rabbits underwent bilateral ACL reconstruction. ADSC constructs were implanted in the right femoral bone tunnel of each rabbit (implant group), while the left knee served as the control group without implantation. Nine rabbits were sacrificed at 3 and 6 weeks post-surgery, while the remaining were sacrificed immediately post-surgery. Biomechanical and micro computed tomography evaluations were conducted on six rabbits, while histological observation was performed on the remaining three. Results: showed: (1) The implant group exhibited a significantly greater failure load than the control group at 3 weeks post-surgery. (2) Initially, the amount of new bone in the femoral tunnel was lower in the implant group at 3 weeks but surpassed that of the control group by 6 weeks. (3) Histological analysis indicated faster bone-tendon healing in the implant group than that of the control. Conclusion: These findings suggest a positive effect of ADSC constructs on bone-tendon healing post-ACL reconstruction in rabbits. However, further studies using larger animal models must confirm these effects comprehensively. The translational potential of this article: The method of transplanting a scaffold-free autologous ADSC construct is a technique that can safely and reliably transplant ADSCs to the tendon-bone tunnel interface without using foreign substances. It can be applied to bone-tendon healing in ACL reconstruction surgery and other areas, such as the rotator cuff and Achilles tendon attachment site.
