Primary Analysis. The primary statistical analysis will compare the six-level primary outcome variable between the randomized treatment groups. The six levels will be assigned scores ranging from 1 (for the most favorable category) to 6 (for the least favorable category), and the mean response score will be compared between the CSA and MMF/Pulse steroid groups within each of the four randomization strata defined by baseline estimated GFR and race. The analysis will be carried out by intent-to-treat. A 2-sided test will be conducted at the 5% significance level.
