TABLE 5.

Analysis of paired comparisons of proportion of decline per week of binding and neutralizing antibody responses^a

^aTest results shown are median difference between groups followed by P value in parentheses. Analysis was by t test assuming unequal variance between groups. Values used for comparison are plasma binding AUC (as shown in Fig. 3) and serum neutralization ID₅₀ titers measured on TZM-bl cells (as shown in Fig. 4). Groups are G1 N2[LpN]2, G2 N2[CpN]2, G3 N2Lp2, G4 N2Cp2, and G5 N2C2 (Table 1). Significant differences are shaded and indicated by asterisks as follows: *, P < 0.05, and **, P < 0.01.
