N = 757. TASSH + HIC sample size: baseline, n = 368; 6 months, n = 302; 12 months, n = 323. HIC sample size: baseline, n = 389; 6 months, n = 303; 12 months, n = 319.

*Effect size is defined as the net difference in systolic and diastolic blood pressure between the 2 groups at 6 and 12 months.

HIC, health insurance coverage; TASSH, task shifting strategy for hypertension control.
