Steroids' Neuroprotective Potential in Severe Cerebral Venous Thrombosis: Experimental and Clinical Exploration of NLRP3 Inflammasome Inhibition.
Article in CNS neuroscience & therapeutics, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundNLRP3 inflammasome-related inflammation might play an important role in the pathophysiology of severe CVT. The use of steroids as anti-inflammatory agents in improving severe CVT prognosis remains controversial.
methodsA total of 94 male Sprague-Dawley rats were used. We evaluated the dynamic and association between NLRP3 inflammasome in brain, blood, and CSF and severity in severe CVT rats and/or patients. We also explored the effect of steroids on NLRP3 activation, neurological injury, and CSF circulation disturbance after CVT in animals and/or patients.
resultsIn rats, compared with the sham group, NLRP3-related factors rose on day 1, peaked on day 2 (NLRP3, Sham: 0.79 ± 0.22; day 2: 1.25 ± 0.08, p < 0.01; pro-Caspase-1, Sham: 0.58 ± 0.13, day 2: 1.20 ± 0.44, p < 0.05; GSDMD, Sham: 0.94 ± 0.22, day 2: 1.72 ± 0.46, p < 0.05; pro-IL-1β, Sham: 0.74 ± 0.15, day 2: 1.35 ± 0.09, p < 0.01), decreased on day 7 in rats (n = 4 per group). Thrombus (Sham: 0.00 ± 0.00, day 2: 3.44 ± 0.70, p < 0.0001), infarct size (Sham: 0.00 ± 0.00, day 2: 11.99 ± 6.26, p < 0.01) and neurological deficits appeared similar trend. In 50 patients, serum NLRP3 and IL-6 levels correlated positively with NIHSS (r = 0.4273, p = 0.0020; r = 0.4938, p = 0.0029) and mRS (r = 0.5349, p = 0.0125; r = 0.6213, p = 0.026), while CSF IL-6 correlated positively with mRS on admission (r = 0.5349, p = 0.0125). Compared with baseline, NLRP3 (0.36 (0.36, 0.36) vs. 0.41 (0.37, 0.84), p < 0.0001) and IL-6 decreased (4.06 ± 1.48 vs. 12.03 ± 7.80, p < 0.05), accompanying by improvement of neurological deficits and CSF circulation (all p < 0.01) after steroids therapy in severe CVT patients at discharge and 3 months follow-up. No significant steroid-related adverse effects were observed.
conclusionShort-term steroid therapy may improve prognosis of severe CVT by suppressing NLRP3 inflammasome-related inflammation.
