Fig. 4From: A parallel genome-wide RNAi screening strategy to identify host proteins important for entry of Marburg virus and H5N1 influenza virusHit selection. a Flowchart of hit selection process. (b and c) Enrichment of hits. For each siRNA, the normalized signal from Marburg virus (MARV) or influenza H5N1 virus (AIV) plates is plotted against the robust z-score of the relative infection index. Hits in area I are classified as specific inhibitory hits against either MARV or AIV entry. Hits in area II are classified as non-specific inhibitory hits against either MARV or AIV entry. Hits in area III are classified as hits that enhance virus entry of either MARV or AIVBack to article page
