Figure 2From: Severe anaemia is not associated with HIV-1 env gene characteristics in Malawian children Phylogenetic tree based on the V1-V2 fragment of the HIV-1 env gene nucleotide sequences. Phylogenetic tree to assess if the HIV-1 genome of children with severe anaemia (cases, Hb<5.0 g/dL) is different from those without severe anaemia (controls). Subtype A and CRF-13 reference sequences are used as outgroup sequence.Back to article page
