Detection of infection in both the full all-age population and detection of infections in the population older than 5 years of age. Some cells are empty because the factor was not retained in the adjusted analysis because they did not contribute to the explanatory power of the model. OR=odds ratio. usPCR=ultra-sensitive PCR.
Mass drug administrations targeting Plasmodium falciparum with or without concurrent long-lasting insecticidal net distribution.
The probability of patients seeking care if febrile is the proxy variable typically used in malaria research to provide a proxy estimate for treatment seeking.
