Note: To avoid the influence of outliers, data in the table - except the UTR counts which are presented as mean ± SD - are presented as median (median absolute deviation). The trends observed are also consistent when using the mean ± SD. The sizes are given in base pairs (bp). All values were rounded to the nearest small whole number.
**
The median values gave 1 (0) and thus the mean ± SD was thought to be appropriate for estimating these values for S. benedictii.
