Examples of levels (Tu) of var transcripts encoding different CIDRα1 subclasses in six children with parasitemia without ongoing fever (A), six children with mild malaria not requiring hospitalization (B), six children hospitalized with uncomplicated malaria (C), six children with severe malarial anemia (D), six children with cerebral malaria (E), and six children who succumbed to infection (F). Bars represent transcript levels reported by primer sets CIDRa1.1 (C1) (red), CIDRa1.8 (C8) (orange), CIDRa1.4/6a (c4) (blue), CIDRa1.5 (C5) (black), CIDRa1.6b (C6) (gray), and CIDRa1.7 (c7) (green). The red line indicates a Tu value of 16.
