Application of Stem Cells in Consolidation Phase of Distraction Osteogenesis: A Systematic Review and Meta-Analysis.
Review in Journal of maxillofacial and oral surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: To systematically review the effect of applying mesenchymal stem cells (MSCs) and gene-therapy approach on the bone formation of the distracted area in the maxillofacial region. Study Design: Studies that delivered genetically modified or unmodified MSCs or used gene-therapy methods without MSCs delivery for the mandibular or maxillary distraction osteogenesis (DO) treatment in both human and animal models were included. Results: From a total of 720, 32 animal studies and one human study were included. Results of human study showed that the injection of bone marrow MSCs has no significant complications and can induce significant bone formation. Results of animal studies showed that applying of MSCs as the study group results in higher values of bone formation variables, namely new bone formation and volume, bone volume/total tissue volume, bone mineral density and thickness of the new trabeculae compared to control group. Meta-analysis revealed that in rabbit models, significant increase was observed in the bone formation percentage after MSCs injection. In the goat models, stem cell injection showed significant increase in trabecular thickness. Conclusion: In animal models, the use of MSCs in distraction osteogenesis (DO) treatment of the maxillofacial region did not result in significant complications and showed potential positive outcomes on bone formation. However, more clinical and animal studies with a lower risk of bias are required to fully establish the efficacy and safety of this approach.
