Blood pressure control rates by treatment strategy

	Blood pressure control rate, %
Treatment strategy	Overall	Black subjects	White subjects
Thiazide diuretic	53.8	55.2	52.4
Age/race	61.3	55.2	67.1
Plasma renin activity	69.4*	62.1**	76.3*

Blood pressure control rate defined as percentage of subjects with BP < 140/90mm Hg. Thiazide diuretic strategy was hydrochlorothiazide in all subjects. Age/race strategy was hydrochlorothiazide in all black subjects and in white subjects aged ≥50 years and candesartan in white subjects aged <50 years. Plasma renin activity (PRA) strategy was hydrochlorothiazide for pretreatment PRA < 0.6ng/ml/h and candesartan for pretreatment PRA ≥ 0.6ng/ml/h.

*P < 0.001 vs. other strategies.

**P = 0.02 vs. other strategies.
