  1. CI, 95% confidence interval.
  2. Denominator is the number of samples with available parasite assessment at time of IPTi application. The difference between the proportion of infected individuals in Kumasi and Lambaréné was always significant with at least p < 0.0006.
  3. a Application of SP or placebo at scheduled time of IPTi.
  4. b One-sided, 97.5% confidence interval.
