  1. Mean and median PQS-to-breakpoint distances are shown for each actual dataset and for two simulated null datasets: breakpoints distributed equally across the genome (equal), or breakpoints distributed according to the number actually observed per chromosome (unequal). The significance of the difference between each actual and null dataset is assessed by calculating a 95 % confidence interval (C.I.) around the sample median: a significant association is noted if the median of the null dataset is outside this confidence interval
