Multivariate linear regression model showing the effect of RTS,S vaccination on levels of IgG to blood stage antigens, compared to control vaccination, adjusted by cohort, age, IFAT titer at baseline, batch of experiments, previous episodes and present infection.

aProportional difference refers to the proportional effect per log-increase in antibody level.
bConfidence Interval.
cR2 value of the OLS regression model was <0.65 in all cases, indicating that only a portion of the variability of IgG data is explained in the model.
