[3] Other relevant method information, such as adjustments or degrees of freedom:
  Repeated measurements analysis (change from baseline over 24 weeks of treatment taking all post-randomization measurements into account).
[4] Additional information, such as whether or not the p-value is adjusted for multiple comparisons and the a priori threshold for statistical significance:
  No adjustment of the significance level (0.05) was done as a hierarchical approach for hypotheses testing was used.
