Figure 5

Response-time plots of ATA titer to the whole F(ab′)2 molecule and anti-CDR ATA positivity status by dose group. Solid light gray bar: pretreatment titer (average of two samples). Solid blue bar: posttreatment titer for anti-CDR negative sample. Horizontal hatched red: posttreatment titer for anti-CDR positive sample. Diagonal hatched yellow bar: posttreatment titer for anti-CDR indeterminate sample.
