Correlation of anaemia and CMt load. The minimum PCV value was negatively correlated with the peak CMt blood load (A) and significantly positively correlated with the length of time between CMt exposure and the first positive PCR result (B). The peak CMt load was significantly negatively correlated with the length of time between CMt exposure and the first positive PCR result (C). The correlations were determined using the Spearman rank correlation test (r and p values indicated in the Figure).
