Bland Altman plot of capillary and venous day 0 parasite density measurement agreement. The difference in simultaneous capillary and venous parasite density measurements on day 0 can be as large as 1.5 log10-fold based on the 95% limit of agreement. The difference may be in either direction, and the variability does not change with magnitude of measurements. Parasite densities represented on a log10 scale
