Endotoxin and viable counts, shown as median (range)
| Surface Median (min–max) | Floor Median (min–max) | Ventilation outlets Median (min–max) | |
|---|---|---|---|
| Spearman’s rank correlation coefficient (rs) is given where significant positive correlation is found between viable counts and PF in the rank correlation test. Modified from Allermann and Poulsen.13 | |||
