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
Fluoride can cause damage to neurons, but the specific mechanisms remain unclear. Neuronal pyroptosis is associated with cognitive dysfunction, but previous studies mainly focused on hippocampal impairments. This study aimed to whether the P2X7R/NF-κB/NLRP3 pathway would trigger pyroptosis in striatal neurons, thereby mediating neurotoxicity of fluoride, and to evaluate the therapeutic potential of salidroside (Sal). Sal, a key bioactive compound derived from Rhodiola rosea, has been reported that it mainly reduces cell pyroptosis by inhibiting the P2X7R/NF-κB/NLRP3 regulatory axis, thereby improving the neurological function in the brain injury models. Therefore, this study explored, this study investigated its potential protective effects against fluoride-induced neurotoxicity. Therefore, an in vivo model of the second-generation (F2) SD rats and an in vitro model of NG108-15 cells exposed to fluoride with Sal intervention were established. The radial arm maze (RAM) was used to measure neurobehavioral changes. Hematoxylin-Eosin (HE) and transmission electron microscopy (TEM) were used to observe histopathological and ultrastructural changes in the striatum of F2 rats. Cell viability and the expressions of pyroptosis-related proteins were measured using biochemical methods. HE staining demonstrated striatal neuronal degeneration in fluoride-exposed groups, the RAM test indicated neurobehavioral defects, and TEM identified ultrastructural neuronal damage. Fluoride activated the P2X7R/NF-κB/NLRP3 pathway, promoting pyroptosis and impairing the memory ability in F2 rats. Mechanistically, Sal mitigated fluoride-induced neuronal loss by blocking P2X7R/NF-κB/NLRP3 signaling and pyroptotic cell death. In summary, these findings suggest the P2X7R/NF-κB/NLRP3 axis mediates fluoride-induced striatal pyroptosis and neurotoxicity, positioning salidroside as a promising therapeutic candidate.
