  1. M male, F female, DM dermatomyositis, MCTD mixed connective tissue disease, PSL prednisolone, mPSL methylprednisolone, sPSL soluble prednisolone, MMT manual muscle test, creatine kinase
  2. aInitial mPSL dose was 1 g × 3 d
  3. bThe first CTs were performed within six weeks before the initial steroid therapy
  4. cSteroid taken using steroid pulse was excluded from cumulative doses of glucocorticoid
  5. dMuscle strength of the bilateral iliopsoas muscle was evaluated using MMT before and after steroid therapy
