Fig. 3.
Serum antibody levels in the patients, their marrow donors, and unrelated controls.
The levels of total IgG2 and specific IgG againstStreptococcus pneumoniae and Haemophilus influenzae capsular polysaccharides did not significantly differ between patients and their donors, whereas the levels of tetanus-specific IgG were lower in the patients compared with their donors. The squares denote medians and the error bars 10th and 90th percentiles. A black star denotes significant difference (P < .05) by paired (Wilcoxon) signed-rank test. A gray star denotes significant difference (P < .05) by Mann-Whitney rank sum test (nonpaired).
