The SMART regimen resulted in higher inhaled corticosteroid exposure ( @ g budesonide per day -LSB- @ -RSB- vs @ g budesonide per day -LSB- @ -RSB- , respectively ; ratio of means @ -LSB- @-@ -RSB- ; p = @ ) , but reduced oral corticosteroid exposure ( @ mg prednisone -LSB- @ -RSB- vs @ mg prednisone -LSB- @ -RSB- , respectively ; p = @ ) , with no significant difference in composite systemic corticosteroid exposure ( @ mg prednisone equivalent per year -LSB- @ -RSB- vs @ mg prednisone equivalent per year -LSB- @ -RSB- , respectively ; @ -LSB- @-@ -RSB- ; p = @ ) .
