The Effectiveness Based on Optimal Dose and Administration Route, and Safety Profiles of Stem Cells and Derived Products in the Treatment of Patients With Amyotrophic Lateral Sclerosis: A Systematic Review and Meta-Analysis.
Review in Stem cells international, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: This systematic review and meta-analysis aimed to evaluate the effectiveness of stem cell therapies for patients with amyotrophic lateral sclerosis (ALS) based on optimal dosing and administration routes, as well as the safety profiles of stem cells and their derived products. Methods: The review followed PRISMA guidelines and involved a comprehensive literature search up to October 2025, receiving ethical approval from Tabriz University of Medical Sciences and registration in PROSPERO. It utilized international databases, including PubMed/MEDLINE, Embase, Cochrane Library, Scopus, Web of Science, ProQuest, ClinicalTrials.gov, and Science Direct. The included studies comprised randomized controlled trials (RCTs), quasi-experimental studies, and other interventional designs involving ALS patients treated with stem cell therapies. In total, 31 studies were analyzed, featuring 7 controlled trials with 370 participants and 24 non-controlled pre-post studies with 460 participants. Heterogeneity was evaluated using Results: A pooled analysis (treatment group: Conclusion: Stem cell therapy for ALS appears to be safe, with preliminary evidence suggesting potential therapeutic benefit in slowing disease progression in selected patients. Nevertheless, the existing evidence base remains exploratory, and definitive conclusions regarding clinical effectiveness cannot yet be drawn. Future research should prioritize large-scale and multicenter RCTs with standardized cell manufacturing protocols and longer follow-up periods.
