  No text entered.
[2] Details of power calculation, definition of non-inferiority margin, and other key parameters:
  The ratio of GMTs (concomitant group / nonconcomitant group) must be greater than 0.67.
[3] Other relevant information, such as adjustments or degrees of freedom:
  ANOVA on natural log titer with fixed effects for region, vaccination group and their interaction.
[4] Additional information, such as whether or not the p-value is adjusted for multiple comparisons and the a priori threshold for statistical significance:
  Since p<0.05, the hypothesis of noninferiority is accepted for this outcome.
