Association of plasma trimethylamine N-oxide (TMAO) concentrations with ischemic stroke
The restricted cubic spline regression was conducted with the use of four knots (placed at the 20th, 40th, 60th, and 80th percentiles of plasma TMAO concentrations) and adjusted for age, sex, BMI, smoking status, alcohol habit, history of hypertension, and history of diabetes. Solid lines are ORs, and dashed lines are 95% CI.
