Association between the QN IC50 and the number of DNNND repeats. The analysis comparing polymorphisms in DNNND repeats was done using the Mann-Whitney test. The horizontal (blue) bars indicate the medians. The numbers of isolates analyzed are shown in brackets. P values comparing the repeats are indicated; 3 DNNND repeats had statistically higher QN IC50 values, compared to isolates with 1 or 2 repeats.
