The BCG growth ratios for each volume of blood used in the BCG-lux assay. (A) Comparing all data for the different volumes of blood used using the Kruskal–Wallis test, n = 12–27 (B) Comparing data that included all three volumes tested using a Friedman ANOVA test and a paired non-parametric Mann Whitney test on comparisons of individual volumes. Each data point represents the average of three replicates from each donor in a given experiment, n = 9. For all tests p ≤ 0.05 was termed significant, ns = not significant.
