Effect of stem cell therapies on tendon-bone healing after anterior cruciate ligament reconstruction in animal models: Protocol for a systematic review and meta-analysis.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionAnterior cruciate ligament (ACL) reconstruction is widely performed, yet insufficient tendon-bone healing remains a key contributor to graft failure. Stem cell-based interventions, including mesenchymal stem cells (MSCs) and stem cell-derived products (e.g., exosomes/extracellular vesicles), have shown potential to enhance tendon-bone integration in preclinical models. However, findings across animal studies are heterogeneous and have not been comprehensively synthesized. This review aims to evaluate the effects of stem cell-based therapies on tendon-bone healing after ACL reconstruction in animal models. METHODS AND ANALYSIS: This protocol follows PRISMA-P. We will search PubMed, Embase, Scopus, SPORTDiscus, Web of Science, and the Cochrane Library from inception to the final search date. Controlled animal studies comparing ACL reconstruction with stem cell-based interventions versus controls will be included. Primary outcomes are biomechanical properties (ultimate failure load and stiffness). Secondary outcomes include micro-CT measures of bone integration (e.g., bone volume fraction, bone mineral density) and histological outcomes (e.g., interface maturation or validated scoring systems). Risk of bias will be assessed using SYRCLE's tool. Random-effects meta-analyses will be performed, with prespecified subgroup analyses by stem cell type, delivery method, animal species, and follow-up time. Sensitivity analyses and publication-bias assessments will be conducted where appropriate. PROSPERO REGISTRATION: CRD420251137985.
