APOB and hypertensive disorder: Logistic regression analysis was performed to determine independent predictors for CI (Table 5), and the results indicated significantly higher risks of CI in the presence of high LDL-C (OR 1.524, 95% CI 1.092–2.100, P = 0.013), and high ApoB (OR 3.046, 95% CI 1.188–7.809, P = 0.020), smoking (OR 1.459, 95% CI 1.166–1.825, P = 0.001), hypertension (OR 2.599, 95% CI 2.136–3.164, P < 0.001), and the ε4 allele (OR 1.822, 95% CI 1.390–2.388, P < 0.001).
