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
Heat stroke (HS) is a life-threatening condition that leads to neuronal injury, particularly in the prefrontal cortex, though its mechanisms remain unclear. In this study, we established a rat HS model and observed significant inflammatory responses and neuronal pyroptosis in the prefrontal cortex 6 h post-heat exposure, with the injury severity increasing over time. Mechanistically, HS activated the caspase-1/GSDMD-dependent pyroptosis pathway through NLRP3 inflammasome activation, resulting in IL-1β and IL-18 release. Additionally, HS caused a marked increase in homocysteine (Hcy) levels in both the serum and the prefrontal cortex, accompanied by reduced expression of the Hcy metabolic enzymes MTHFR and CSE, suggesting Hcy metabolism disruption. In vitro, Hcy induced pyroptosis in PC12 cells, elevating IL-1β, IL-18, and LDH levels. Notably, the NLRP3 inhibitor MCC950 mitigated this effect by reducing IL-18 and LDH release. Reducing Hcy in vivo alleviated neuronal pyroptosis and counteracted the YTHDF2-mediated decrease in NLRP3 mRNA m
