^aDisease type and incidence was compiled from [23, 44, 57–65].

^bMany Emvs have assigned numbers [6, 46]; Emv+, strains carrying uncharacterized PCR-detected Emv env sequences.

^cExpression is identified as: SpH, spontaneous high; SpL, spontaneous low; Ag+, viral antigen positive; Ind, inducible by iododeoxyuridine; -, no expression; NT, not tested.

^dThe X/P-MLV ERVs that contribute to P-MLVs were previously identified [13].
