RESULTS
Plasma TMAO levels were higher in patients with ischemic stroke than in healthy controls (median 5.1 vs 3.0 μmol/L; p < 0.001). Every 1-µmol/L increase in TMAO was associated with a 1.13-point increase in NIHSS score (95% confidence interval [CI] 1.04-1.29; p < 0.001) and 1.69-mL increase in infarct volume (95% CI 1.41-2.03; p < 0.001) after adjustment for vascular risk factors. At admission, 159 patients (42.2%) had experienced a mild stroke, and their plasma TMAO levels were lower compared to those with moderate to severe stroke (median 3.6 vs 6.5 µmol/L; p < 0.001). The area under the receiver operating characteristics curve of plasma TMAO level in predicting moderate to severe stroke was 0.794 (95% CI 0.748-0.839; p < 0.001), and the optimal cutoff value was 4.95 μmol/L. The sensitivity and specificity of TMAO levels ≥4.95 μmol/L for moderate to severe stroke were 70.2% and 79.9%, respectively.
