Comparison with seroconversion rate a Association of median estimates of exposure rates for different villages estimated using the antibody density model (x-axis) and the catalytic model (y-axis) using both European control (squares) and a mixture model to define the cut-off (circles). Note that the two measures are not equivalent but are highly correlated. b Plot of coefficient of variation (standard deviation of posterior/mean of posterior) of the exposure rate estimated from both the density model (black circles) and the catalytic model (x) using European controls. Data are presented for each village categorized by transect
