| Variables | Adjusted odds ratio (Exp β) | 95% CI | p |
|---|---|---|---|
| Duration of cigarette smoking | 0.968 | 0.944; 0.992 | 0.010 |
| Salt (1)a | 2.282 | 0.593; 8.787 | 0.230 |
| Salt (2)a | 0.118 | 0.047; 0.297 | <0.001 |
| Taking CCB | 3.080 | 1.116; 8.501 | 0.030 |
| Postpone physician visits | 0.245 | 0.110; 0.543 | 0.001 |
| Know normal BP value | 4.948 | 1.517; 16.134 | 0.008 |
BP = blood pressure; CCB = calcium channel blockers; CI = confidence interval; DBP = diastolic blood pressure. Dependent variable: dichotomized Morisky score. Omnibus test p-value < 0.001/Hosmer–Lemeshow test p-value = 0.986.
Nagelkerke R2 = 0.362/Overall predicted percentage = 83.7%.
