Figure 3

Likelihood values of PRT4 and MLPA shown as box plots. Box represents the region between the first and the third quartile (i.e. the central 50 % of the data). The horizontal line in the box represents the median. The end of the vertical line marks the smallest likelihood value located less than 1.5 times the interquartile distance from the first quartile. Other observations may be deemed outliers and are shown as dots. ***P < 0.001 in a Mann–Whitney test.
