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/purpose: Osteoporosis in the jawbone can compromise the success of dental implant treatment. Human umbilical cord mesenchymal stem cells (hUCMSCs) have demonstrated osteogenic differentiation potential. This study aimed to evaluate the effect of hUCMSC induction on implant osseointegration in an osteoporotic animal model. Materials and methods: Twenty-eight osteoporotic female Wistar rats were divided into control and hUCMSC-induced groups and observed at 2 and 4 weeks. The treatment group received hUCMSC injections into the implant area of the femur osteoporotic model. Specimens were stained using immunohistochemical and haematoxylin and eosin techniques to assess osteogenic marker expression. Data were analysed using Kruskal-Wallis and Mann-Whitney U test. Results: Bone-implant volume (BIV) was significantly greater in the hUCMSC-induced groups compared to controls. The expression of osterix, RUNX family transcription factor 2 (RUNX2), tumor necrosis factor (TNF)-α, nuclear factor of activated T cells 1 (NFATc1), collagen type 1, and osteocalcin decreased in osteoblasts from week 2 to week 4. Significant differences ( Conclusion: Induction with hUCMSCs promotes both early and late osseointegration in osteoporotic animal models. These results highlight the efficacy of hUCMSCs in enhancing bone healing after implant placement under osteoporotic conditions.
