↵a Arbitrary units.
↵b One sample with responses of 43,136 U and 46,336 U to the Triton and recombinant 27-kDa antigens, respectively, was considered an outlier and omitted.
↵c Mean values were significantly different from those of other serum sets and from each other when a multiple-comparison t test was used. The P values for all comparisons were <0.0104.
↵d Mean values were significantly different from those of other serum sets and from each other when a multiple-comparison t test was used. The P values for all comparisons were <0.0226.
