Effects of Simplified Antihypertensive Treatment Algorithm on Hypertension Management and Hypertension-Related Death in Resource-Constricted Primary Care Setting between 1997 and 2017

Table 2

Changes in awareness, treatment, and control of hypertension between 1998 and 2015 (n, %).

	1998–2000		2007-2008		2015		X^2/ value
	n	% (95% CI)	n	% (95% CI)	n	% (95% CI)
Awareness	293	33.4 (30.3,36.5)	576	50.8 (47.9,53.8)	353	53.3 (49.5,57.1)	85.29/<0.001
Treatment	98	11.2 (9.1,13.3)	263	23.2 (20.8,25.7)	215	32.1 (28.9,36.1)	101.86/<0.001
Control 1	2	0.2 (0.1,0.5)	30	2.6 (1.7,3.6)	72	10.7 (8.5,13.3)	120.85/<0.001
Control in the treated	2	2.0 (0.8,4.9)	30	11.4 (7.5,15.3)	72	33.5 (27.1,39.8)	59.46/<0.001
Control 2	1	0.1	12	1.1	34	5.1	59.84/<0.001

n: the number of hypertensives with awareness, under treatment, with blood pressure controlled. Control 1 was defined as BP < 140/90 mmHg; control 2 was defined as BP < 130/80 mmHg.
