1 · What the graph read from it

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.

2 · The registry

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

The regulation of the hair cycle is orchestrated by a complex network of signaling pathways, and substantial evidence from extensive research indicates that exosomal miRNAs may play a pivotal role in this process. In this study, we present compelling evidence that exosomes derived from human umbilical cord mesenchymal stem cells (hUC-MSCs), pretreated with the Wnt pathway agonist lithium chloride (LiCl), significantly enhance hair regeneration. High-throughput sequencing was utilized to identify differentially expressed miRNAs in exosomes from both LiCl-pre-treated and untreated groups, thereby elucidating potential mechanisms underlying this phenomenon. Specifically, miR-146a-5p was found to activate the Wnt signaling pathway, thereby promoting the proliferation and migration of primary dermal papilla cells in mice. The downstream target genes of miR-146a-5p, including SFRP1, SMAD2, SMAD4, and EGFR, were predicted using bioinformatics tools and subsequently validated through experimental validation. An animal model overexpressing miR-146a-5p was constructed, demonstrating that miR-146a-5p targets SFRP1 to promote hair regeneration in mice via activation of the Wnt signaling pathway.
