OTHER_PRE_SPECIFIED outcome

Timeframe: 24 Months

Population: Although the protocol specified analyses of serum biomarkers as secondary outcomes, the intent was to only perform these analyses if the primary endpoint showed sufficient efficacy. Given the lack of efficacy of steroids (vs placebo), the analyses of fat-soluble vitamins were not performed; thus, data are not summarized for this assessment.

Vitamin E sufficiency is measured as the ratio of serum vitamin E/total lipids
