  1. MSTCQ, Multiple Sclerosis Treatment Concern Questionnaire; SD, standard deviation.
  2. *Maximum score = 20 for ISR and FLS, 15 for GSE; higher scores indicate greater negative impact. Further information on the use of the MSTCQ to assess satisfaction with injection systems for subcutaneous interferon beta-1a can be found in [13].
