From: Quantification of the dynamics of antibody response to malaria to inform sero-surveillance in pregnant women

  Number of controlsd classified into Cluster 1 (%) Number of casese classified into Cluster 2 (%) Total women classified into the expected Clusterf (%)

  1. aCluster 1 (low immunity group)
  2. bCluster 2 (high immunity group)
  3. cAntibodies are ordered from the highest to the lowest percentage of classifying pregnant women into the expected cluster
  4. dOut of 115 controls
  5. eOut of 135 cases
  6. fComputed based on the decision made that Cluster 1 would represent controls and Cluster 2 would represent cases. The sum of controls classified into Cluster 1 and cases classified into Cluster 2 were then divided by the total pregnant women, i.e. 250 to obtain the percentage
