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: Dental surgery is a common treatment for pulpitis, which can lead to decreased pulp vitality. A novel approach is needed to induce reparative dentin formation without pulp removal. Ginsenoside Rb1 (G-Rb1) is known for its regenerative properties in various diseases. This study aimed to examine the odontogenic differentiation-promoting effects of G-Rb1 in human dental pulp stem cells (hDPSCs) and a rat pulpotomy model, and explore the underlying molecular mechanisms. Methods: hDPSCs were extracted from supernumerary teeth and cultured with 10 μg/mL G-Rb1. Odontoblastic differentiation was assessed through real-time PCR, western blot, ALP activity, and Alizarin Red S staining. RNA sequencing was performed to confirm the effects of G-Rb1 on odontogenesis of hDPSCs. The effects in the rat pulpotomy model were evaluated by examining reparative dentin formation using von Kossa staining. Results: G-Rb1 was non-cytotoxic and significantly enhanced hDPSC migration and odontoblastic differentiation in hDPSCs, upregulating the expression of odontogenic markers, DMP1 and DSPP, and increasing mineralized nodule deposition. RNA sequencing identified the TGF-β/Smad pathway as a key mechanism underlying these effects, which was confirmed by evaluating the expression of pathway-related proteins. Conclusion: G-Rb1 promotes odontoblastic differentiation in hDPSCs and enhances reparative dentin formation via the TGF-β/Smad signaling pathway. These findings highlight the potential of G-Rb1 as a therapeutic agent for dental pulp repair and regeneration.
