Figure 6

Distribution of negative-log-likelihood ratio between the models.
PH group (left blue distribution) and non-PH group (right red distribution). A Gaussian curve is fitted for each distribution and can be seen overlaid on the distributions. The means for the PH and non-PH groups are 0.9 and 1.1 respectively, with a standard deviation of 0.1 for each group. x-axis shows the negative-log-likelihood ratios, and the y-axis shows the frequency.
