Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Subjects recruited from 20 medical centers from June 2003 to August 2005.

Reporting Groups
  Description
IGF-1 The insulin-like growth factor type 1 (IGF-1) arm was the active treatment group. They received 0.05 mg/kg body weight administered subcutaneously twice daily.
Placebo Placebo group received the equal volume (based on kg of body weight) of the inert suspension vehicle in which the IGF-1 was suspended.
