Adjusted ORs of normalized blood pressure in hypertensive patients after health education intervention

Variable	Normalized blood pressure (<140/90 mmHg)
	OR a	(95% CI) c	P
Interventiond
Group 1 self-learning reading	1.00
Group 2 regular lecture	2.37	(1.26-4.47)	0.008*
Group 3 interactive workshop	14.66	(6.59-32.62)	<0.001*
Baseline characteristicb
Hypertension knowledge score	1.06	(0.81-1.38)	0.676
Systolic BP	0.58	(0.43-0.79)	0.001*
Diastolic BP	0.80	(0.59-1.07)	0.134
Serum TG	0.88	(0.66-1.17)	0.369

^aThe odds ratios of normalized blood pressure (<140/90 mm Hg) in the final model including the intervention group and baseline characteristics unbalanced between the groups (hypertension knowledge score, systolic BP, diastolic BP, serum TG and HDL).

^bThe OR per SD increase in each continuous variable.

^cCI=confidence interval.

^dThe reference category was “Group 1 self-learning reading”.
