Flowchart of the simulation model used to mimic the within-host dynamics of P. falciparum infections. Bi(a,b) represents the use of a binomial distribution with sample size a and probability b. When a was large, a normal distribution was used as an approximation of the binomial. N(a,b) represents the use of a normal distribution with mean a and standard deviation b. Ab, antibody; NSI, nonspecific immunity.
