Primary

MeasureTime frame
Threshold value based on logistic regression and ROC analysis using specific antibody titer against influenza virus antigen and success/failure of virus isolation test

Secondary

MeasureTime frame
Sensitivity, specificity, and ROC-AUC were determined by logistic regression and ROC analysis using specific antibody titers against influenza virus antigens and the success or failure of virus isolation tests.
