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
To establish a standardized 3D human dermis model for evaluating the biological and mechanical effects of non-invasive monopolar radiofrequency (NMRF) treatment. Collagen-based 3D dermal constructs with human dermal fibroblasts were fabricated via bioprinting and treated with NMRF. Histology, immunofluorescence, SEM, and compression tests were conducted to assess tissue remodeling. Conditioned media from treated constructs were applied to fibroblasts, melanocytes, and keratinocytes to evaluate paracrine effects on migration, pigmentation, and oxidative stress. NMRF treatment led to increased fibroblast activity and cellular enlargement, along with the formation of a denser and more organized collagen network, as demonstrated by histological and SEM analyses. Immunofluorescence staining revealed a marked increase in type I collagen deposition surrounding activated fibroblasts. Biomechanical testing showed a significant rise in compressive modulus and reduction in tissue dimensions, indicating enhanced dermal stiffness and matrix remodeling. Furthermore, conditioned media derived from NMRF-treated constructs significantly promoted fibroblast migration in wound healing assays, suppressed the expression of melanogenesis-related genes (MITF, tyrosinase, Trp-1, and Trp-2) in α-MSH-stimulated B16F10 melanoma cells, and improved the survival of keratinocytes exposed to oxidative stress (H₂O₂). This 3D dermis model enables reproducible assessment of NMRF-induced dermal remodeling. NMRF improves dermal structure and modulates paracrine signals, suggesting therapeutic potential in skin tightening, pigmentation control, and tissue regeneration.
