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: Human hair follicle epithelial stem cells (hHF-EpSCs) represent a promising cell source for biomedical research. However, conventional 2D culture systems show limited efficacy in maintaining their stemness and proliferative capacity. Methods: In this study, we compared two 3D culture strategies: Embedding EpSCs in Matrigel (embedded culture) and seeding them on top of Matrigel (on-top culture). The formation, quantity, and size of the spheres were observed by microcscope. The cell viability and proliferation were assessed by staining Calcein AM/Propidium iodide (AM/PI) and Water-Soluble Tetrazolium 1 (Wst1) assay. The expression of EpSC specified markers such as CD200, CK19, CK15, CK10, CK5 were found via immunocytochemistry. The genes related to hair-induction, including Results: The embedded approach facilitated the formation of numerous cell aggregates with an average size below 200 μm, peaking in number on day 10 (88.33 ± 4.16 spheroids per microscopic field). In contrast, the on-top culture produced fewer aggregates (maximum 17.00 ± 1.00 per microscopic field on day 3), with larger average sizes (>200 μm). Cells cultured within Matrigel also exhibited higher viability and proliferation over 14 days. Both methods preserved the expression of key HF-EpSC markers, including CD200, CK19, CK15, CK10, and CK5. The upregulation of genes such as Conclusion: These findings suggest that 3D Matrigel-embedded culture is a promising approach for maintaining EpSCs, and promoting hair induction.
