Association of RV Detection with Bacteria Quantity1.
| Bacteria Quantity Detected (CFUe) | RV Detection (%) | p-value | ||||
|---|---|---|---|---|---|---|
| vs. no bacteria | vs. lower half/lowest quartile | vs. 2nd quartile | vs. 3rd quartile | |||
| M. catarrhalis | 0 | 38% | - | - | - | - |
| 1–202 | 45% | 0.42 | - | - | - | |
| 203–161,000 | 53% | 0.07 | 0.45 | - | - | |
| S. pneumoniae | 0 | 35% | - | - | - | - |

| 323–8,770,000 | 73% | <0.0001 | 0.0002 | - | - | |
| H. influenzae | 0 | 37% | - | - | - | - |

0 = below detection. Detectable bacteria were divided into above and below median. Because we detected H. influenzae in a large quantity of samples we divided this group into quartiles.
