CHI3L1 and ischemic stroke: Both continuous and 4th quartile YKL-40 values were predictive of all-cause mortality with HRs of 1.23 (95% CI, 1.11–1.36) and 1.40 (95% CI, 1.15–1.71), p<0.0001, and 4th quartile YKL-40 values were also predictive of mortality of ischemic stroke after multivariate adjustement (HR 2.44 (95% CI, 1.03–5.88), p = 0.041) (Table 3).
