Groups2

Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.

GroupTitleDescriptionWith the outcomeAnalysedClinicalTrials.gov code
Group 1Anti-hypertensive Therapy to Goal <140/90 mmHg
Labetalol or Nifedipine ER will be used as first-line to achieve goal; if necessary Nifedipine ER or Labetalol will be second-line antihypertensive. Rarely, other antihypertensive medications may also be used~Anti-hypertensive therapy: 1st line anti-hypertensive (Labetalol or Nifedipine ER) started; escalate to maximum dose and a preferred 2nd line medication if needed (nifedipine ER or Labetalol)
5921,208OG000
Group 2No Anti-hypertensive Unless BP is Severe (≥160/105 mmHg
Antihypertensive therapy given only if BP becomes severe (defined as BP ≥160/105). The lowest dose of anti-hypertensive needed to keep blood pressure below this threshold will be given (1st-line - Labetalol or Nifedipine ER and 2nd-line - Labetalol or Nifedipine ER). Rarely other medications may be used~No anti-hypertensive therapy (unless BP is severe): Treatment will not be started if blood pressure remains \<160/105; for blood pressure ≥160/105, treatment with labetalol or Nifedipine ER will be initiated and maintained at lowest dose needed to keep blood pressure under 160/105.
