ONSD was also measured on the initial CT or MRI. The primary endpoint of IH was a composite of clinical and radiological signs of brain swelling.

The initial sonographic ONSDint was significantly increased in patients who developed IH. The multivariable model identified an optimal predictive cut-off of ⩾5.51 mm, which predicted IH with a sensitivity of 85.7% and a specificity of 94.8%. In comparison, ONSD derived from initial neuroimaging was also a strong predictor, with an optimal cut-off of 6.80 mm yielding a sensitivity of 100% and a specificity of 91.1%, and showed superior predictive accuracy in the cross-validation (AUC 0.905 vs 0.687).</p><p><strong>Discussion: </strong>Our sonographic ONSDint cut-off of ≥5.51 mm aligns well with recent stroke literature that used similar standardized measurement techniques. Our findings also highlight the distinct roles of different imaging modalities.

However, its prognostic role after ischemic stroke in other populations is not yet comprehensively investigated.</p><p><strong>Patients and methods: </strong>We measured plasma TMAO levels in 1726 acute ischemic stroke patients (within 24 h from symptom onset) from the multicenter BIOSIGNAL cohort. Using cox and logistic regression models adjusting for demographic and vascular risk factors, we investigated the association of TMAO with recurrent stroke, MACE within 365 days and functional outcome at 90 days after stroke.</p><p><strong>Results: </strong>TMAO levels were not associated with any risk of recurrent stroke (<i>n</i> = 108, unadj.
