Antibody levels associated with age and village altitude for MSP-1₁₉ antigens. Black dots indicate median estimates of antibody density for the actual data for each village, while median and 95 % credible intervals are represented in red for the model fit (line for median and shaded area for the credible interval). In each transect (each column), villages are presented with decreasing altitude/increasing transmission intensity from top to bottom
