  1. aBased on the mean of 10,000 iterations. 1,000 random spacers were sampled per iteration.
  2. bEmpirical p-value based on the fraction of times the estimated percentage of shared spacer groups for each subject or sample type exceeds that for different subjects or sample types. P-values ≤0.05 are highlighted in bold.
