Fig. 4From: Development of an objective gene expression panel as an alternative to self-reported symptom scores in human influenza challenge trials a The predicted DSS from the qRT-PCR based assay using the deltaCt values from the 19 gene signature as a test dataset were plotted against the observed DSS. b The importance of individual markers within the panel of 19 primers is shown in decreasing importance. The x-axis shows the increase in RMSE if the respective gene is left out of the model. LVS live viral shedding assayBack to article page
