  1. Mann-Whitney U Test was used to calculate the numbers of bacterial differences at the different culture sites in CFU/mL between the groups
  2. IQR interquartile range
  3. *Statistically significant difference. Entries in bold face represent significantly more bacterial growth and its relationship with the significance in P-value
