^aR² values as a measure for the variability explained by the antibody level at 100 days after infection (int100), the slope of the antibody kinetics within 30 days (slope30), and a combination of both (R² both).

^bThe clinical baseline parameters of age, gender, WHO peak, immunodeficiency, and multimorbidity were additionally considered.
