Reporting Groups
  Description
Peginterferon+Ribavirin peginterferon alpha-2a, 180 ug subcutaneous once weekly and weight-based oral ribavirin (1000 mg daily for patients less than 75 kg and 1200 mg daily for patients greater than 75 kg) for 48 weeks
Peginterferon Alone peginterferon-alpha 2a, 180 ug subcutaneous once weekly for the first 4 weeks of therapy, after which peginterferon was continued at the same dose and weight-based oral ribavirin was added and continued for an additional 44 weeks.
