The highest quartiles of IL-6 (adjusted HR, 1.36; 95% CI 1.13–1.64; P = 0.001), hsCRP (adjusted HR, 1.41; 95% CI 1.17–1.69; P = 0.0003) and YKL-40 (adjusted HR, 1.28; 95% CI 1.06–1.56; P = 0.01) were associated with increased risk of recurrent stroke; and the highest quartiles of IL-6 (adjusted OR 1.93; 95% CI 1.64–2.27; P < 0.0001), IL-1Ra (adjusted OR 1.60; 95% CI 1.37–1.87; P < 0.0001), hsCRP (adjusted OR 1.60; 95% CI 1.37–1.86; P < 0.0001) and YKL-40 (adjusted OR 1.21; 95% CI 1.03–1.42; P = 0.02) were correlated with increased risk of poor functional outcome. Here, CHI3L1 is linked to Stroke.
