4. Decrease in dose of prednisone or other immunosuppressive drugs by 25% Statistical Analysis The primary outcomes are the means of paired pre vs. post galactose treatment differences in FSPF, urine protein: creatinine ratio, serum albumin and dose of immunosuppressive drugs. We will use repeated measures ANCOVA models to estimate each primary outcome as the dependent variable while holding constant pre-treatment levels. Therefore, the independent variable will be the pre-treatment level of the corresponding dependent variable, The model will be used to estimate the mean difference +/- the 95% confidence interval (CI) corresponding to the mean level of the dependent variable at pre-treatment. We will consider the pre-post difference to be statistically significant if the 95% CI around the result fails to include 0 and to be clinically significant if it meets the criteria specified above.
