Age-stratified adjusted odds of heavy Plasmodium spp. infection compared to light infections among infected individuals.

Values within the table represent OR and 95% CI. Bold font indicates a significant adjusted OR. Models were derived by stepwise elimination of the least significant correlates variables as identified by Wald test criteria. Original correlates also included grand mean centered age among relevant population (children or adults), sex, recent malaria treatment, malaria knowledge, attitudes and practices, regular income (for adults model only), and household socio-economic position.‡Ordinal variable with values 0–4 representing increasing intensity. Categories based on distribution of infection intensities in the study population.
