Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Of the 758 participants randomized and treated in study 24735 (NCT00078338), 326 were enrolled in EMR200136_023 (NCT01034579) out of which 2 participants, who had participated in initial pharmacogenetics (PGx) sub-study, were found to be ineligible and therefore, evaluable population for EMR200136_023 (NCT01034579) comprised of 324 participants.

Reporting Groups
  Description
Rebif® Cohort Participants who had received Rebif® 44 microgram (mcg) three times a week for 96 weeks in study 24735 (NCT00078338) and not participated in the initial PGx sub-study were enrolled in this retrospective cohort study wherein single blood sampling was performed for pharmacogenetic markers analysis.
Copaxone® Cohort Participants who had received Copaxone® (Glatiramer Acetate) 20 milligram once daily for 96 weeks in study 24735 (NCT00078338) and not participated in the initial PGx sub-study were enrolled in this retrospective cohort study wherein single blood sampling was performed for pharmacogenetic markers analysis.

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Evaluable population included all randomized participants who had received at least 1 dose of Rebif® or Copaxone® in 24735 (NCT00078338) and not participated in the initial PGx sub-study and provided consent to take part in this EMR200136_023 study (NCT01034579).
