Self-monitoring vs usual care: threshold level of significance P = .05.
Sustained elevated blood pressure defined as 2 readings ≥140/90 mm Hg within 168 hours or a recorded diagnosis of pregnancy hypertension or prescription of an antihypertensive medication, whichever came first.
Difference in percentage of having elevated blood pressure modeled against randomized group, parity, and site.
