Statistical analysis was performed using JMP (Carey, NC). Box-Cox transformation of raw data was performed to correct non-normal distribution of the data and residuals. Improvements were assessed by Shapiro-Wilk W test of the transformed data and residuals. Means were compared within diagnosis by Oneway analysis using both Student’s T test and Tukey Kramer HSD. Finally, a nested analysis of values for individual patients was performed using standard least squares analysis comparing means for all pairs using Student’s T test for specific pairs and Tukey Kramer HSD for multiple comparisons.
