Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Pregnant women were recruited at 18 private (15) and university (3) medical centers from May 2003 through February 2008.

Reporting Groups
  Description
"Rescue" Course of Betamethasone or Dexamethasone Receive 2nd "Rescue" Course = Study drug (betamethasone or dexamethasone. If Dexamethasone, administered 6 mg IM q 12 hours x 4 doses total. If Betamethasone was used, 2 doses of 12 mg of betamethasone was given intramuscularly (IM) 24 hours apart.
Placebo (Normal Saline)

Placebo consisted of quantity sufficient of Normal Saline with preservatives, Benzylalcohol and Benzylbenzoate.

The research subject received 2 doses of pharmacy prepared placebo (2ml normal saline)to conceal administration of dexamethasone or if to conceal betamethasone, 2 doses of Placebo (2ml normal saline) given IM 24 hours apart.
