TABLE 5.
Estimated odds ratios for administration of specific antibiotics within 5 days of the first visit when an H. influenzae strain was identified (n = 153b) and eradication of the strain within 6 weeks
| Antibiotic administered | Odds ratio | 95% confidence interval |
|---|---|---|
| No antibiotic (reference) | ||
| Macrolide | 1.89 | 0.43–8.30 |
| Fluoroquinolone | 31.48 | 8.53–116.14 |
| Other antibiotica | 1.15 | 0.43–3.10 |
a
Other antibiotics included cephalosporins, penicillins, sulfa drugs, and all others.
b
We eliminated from analysis 14 strains that we could not confirm as recent-acquisition isolates; 11 were present at the first study clinic visit, and two were isolated from participants with more than three missing visits prior to strain isolation. One additional strain was eliminated because the participant did not have a follow-up visit.
