  1. iiic – odds ratio with 95% confidence intervals, d – p-value.
  2. ivThe association of clinical symptoms with malaria infection as determined by RDT positivity was determined by logistic regression with GLMMs controlling for age and seasonality as fixed effects and for date, individual nested in CHW and CHW nested in cluster location as random effects.
