Gene expression associated with inactivated influenza vaccine (IIV) seroconversion. Classification And Regression Trees analysis was performed on 46 patient samples comparing seroconversion status of each IIV strain with differential gene expression (n = 184). The magnitude of the change in gene expression between day 0 and day 7 was utilized to identify the depicted node structure. IIV seroconversion was fit with a receiver operating characteristic curve value of 0.72 (specificity, 67.4%; sensitivity, 59.2%).
