Fig. 3From: Quantifying malaria endemicity in Ethiopia through combined application of classical methods and enzyme-linked immunosorbent assay: an initial step for countries with low transmission initiating elimination programmeDistribution of total malaria antibody optical density readings at an absorbance reading of 450 nm for the whole sample, Ethiopia, June 2016. The mean OD was 0.42 (SD = 0.94) for the whole sample. The distribution was skewed to the left indicating that the absorbance value was low for large percentage of the sampleBack to article page
