Impact of MSAT interventions on P. falciparum incidence and prevalence. Random-effects (RE) meta-analysis model for studies grouped according to the comparator and effect measure used to assess the impact of mass screening and treatment (MSAT) on P. falciparum incidence, using incidence rate ratio (IRR), or P. falciparum prevalence, using the odds ratio (OR) or prevalence ratio (PR). Multiple estimates were included for studies which delivered or measured the impact of MSAT using multiple methods
