Correlation analysis of IgG, IgG1, and IgG3 antibody responses in two PvDBP-II variants with host age and exposure
| Age | Exposure | |||
|---|---|---|---|---|
| Correlation coefficient | P value | Correlation coefficient | P value | |
| IgG (I) | r = 0.289 | 0.007 | r = 0.362 | 0.001 |
| IgG (VI) | r = 0.331 | 0.002 | r = 0.354 | 0.001 |
| IgG1 (I) | r = 0.148 | 0.177 | r = 0.411 | < 0.0001 |
| IgG1 (VI) | r = 0.164 | 0.135 | r = 0.312 | 0.004 |
| IgG3 (I) | r = 0.068 | 0.537 | r = 0.037 | 0.739 |
| IgG3 (VI) | r = 0.051 | 0.645 | r = 0.009 | 0.932 |
The P value denotes the Spearman's correlation coefficient test. P value < 0.05 was considered significant. I = PvDBP-I; VI = PvDBP-VI; r = correlation coefficient.
