OCLN and hematocrit: The multivariate logistic regression indicated that the baseline serum occludin level (OR 4.969; 95% CI 2.609–11.935, p < 0.001) and baseline NIHSS score (OR 1.293; 95% CI 1.079–1.550, p = 0.005) were significantly associated with HT even after adjusting the effects of the other three factors (Table 2).
