  1. aAn a priori probability of success (k/n) in each trial equals to 0.044, which was the overall prevalence of anopheline-P. falciparum infection obtained herein (21 /480), was assumed.
  2. bThis result was statistically significant (level of significance < 0.05).
  3. cThis result shows that the statistical power was low (<0.80).
