Translating umbilical cord blood extracellular vesicles into a novel therapy for postpartum alopecia: a mechanistic and preclinical review.
Review in Frontiers in immunology, 2026. 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
Postpartum alopecia (PPA) is a common physiological hair loss in women, characterized by complex pathogenesis involving abrupt postpartum hormonal withdrawal, disrupted hair follicle cycling, local microenvironmental inflammation, and oxidative stress. Umbilical cord blood-derived extracellular vesicles (UCB-EVs)-nanosized, lipid-bilayer-enclosed particles enriched with microRNAs, growth factors, and proteins-have shown considerable promise in regenerative medicine owing to their low immunogenicity, high biocompatibility, and tissue-repair capacity. This review systematically summarizes the current state of research on UCB-EVs in the context of PPA, focusing on their proposed molecular mechanisms in hair follicle regeneration, hair-cycle modulation, antiinflammatory effects, and antioxidative stress responses. Importantly, the available evidence remains largely preclinical, derived from
