Figure 3. Association between Lewis blood group and immune responses following cholera.

Figure 3

The Signed rank test was used to compare antibody responses on different days. The Mann Whitney U test was used to compare immunologic responses in patients of different Lewis blood groups. Asterisks indicate significantly higher responses at convalescence (day 7 and day 30) compared to that in acute stage (day 2), using a paired t-test. Brackets denote statistically significant lower LPS-specific IgA responses on day 7 in patients with the Le(a–b—) phenotype compared to the other two groups.
