FIGURE 2.

Probability of remaining free of malaria re-infection amongst individuals with different anti-PfRh5 antibody levels. Time-to-first PCR-positive P. falciparum blood-stage infection (A), LM-positive (B), LM-positive with ≥500 parasites/μL (C) and LM-positive with ≥5000 parasites/μl (D) in individuals with low, medium or high anti-PfRH5-specific antibody titers at study enrolment, as determined by Kaplan–Meier survival analysis. Log-rank was used to determine differences among responder groups, p < 0.0001 between high and low responders and p = 0.019 between medium and low responders with LM ≥ 5000 parasites/μl.
