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
Small extracellular vesicles (sEVs) derived from mesenchymal stem/stromal cells (MSCs) contain microRNAs (miRNAs) that can modulate the cellular behavior of recipient cells. Human periodontal ligament mesenchymal stem/stromal cells (hPDL-MSCs) are a unique MSC population involved in periodontal tissue regeneration; however, the specific miRNAs that regulate their proliferative and differentiation-related properties remain incompletely understood. In this study, we profiled miRNAs enriched in sEVs secreted by highly proliferative human PDL-MSCs and identified hsa-let-7c-3p as a candidate regulator of hPDL-MSC behavior. Functional assays demonstrated that hsa-let-7c-3p enhanced proliferative and migratory behavior, reflected by an approximately 1.5-fold increase in metabolic activity and a 2-fold increase in migration, while suppressing osteogenic differentiation, with approximately 50% reductions in alkaline phosphatase activity and mineralization. To identify functionally relevant downstream targets, we intersected AGO2-RIP-seq-enriched transcripts, RNA-seq-defined genes altered by hsa-let-7c-3p overexpression, and in silico target predictions, identifying NT5E/CD73 as a candidate downstream target with experimental validation. Furthermore, NT5E knockdown partially phenocopied the effects of hsa-let-7c-3p overexpression on hPDL-MSC proliferation, migration, and osteogenic differentiation, supporting a functional link between hsa-let-7c-3p and NT5E/CD73. These findings highlight hsa-let-7c-3p as an underexplored sEV-associated 3p miRNA strand that restrains the proliferation-to-osteogenesis transition of hPDL-MSCs and identify NT5E/CD73 as a functionally relevant downstream target.
