FIG 1.

Comparison of paired OF and plasma samples, expressed as S/CO values. (Left) One hundred seropositive (n = 131 paired samples) and 13 seronegative individuals in the IgG-capture assay. (Right) Thirty-six seropositive and 8 seronegative individuals in the Murex HTLV I+II EIA. Black dots, samples from seropositive individuals; red dots, samples from seronegative individuals. Solid horizontal bars show median. The horizontal dashed line indicates the S/CO at 1.00, above which samples are considered reactive.
