RNA abundance of different EBV reference sequences in EBV positive persons. Colour scale from blue to red indicates low to high abundance. Subtype of GenBank accession ID is used as name for each EBV reference sequence on x-axis. Persons were clustered according to Euclidean distance measure of abundance values (dendrogram on the left). Age group of each person is indicated by side bar (grey: age < 60, black: age ≥ 60)
