|||
|---|---|---|---|
| Treatment | Patients | Same Strain | Different Strain(s) |
| Vancomycin (no.) | 62 | 51 | 11 |
| Recurrence 1–14 d after treatment (no.) | 46 | 39 | 7 |
| Recurrence 15–30 d after treatment (no.) | 16 | 12 | 4 |
| Mean time to recurrence, d (±SD) | 11.7 (±6.4) | 11.2 (±6.1) | 13.9 (±7.5) |
| Fidaxomicin (no.) | 28 | 24 | 4 |
| Recurrence 1–14 d after treatment (no.) | 14 | 13 | 1 |
| Recurrence 15–30 d after treatment (no.) | 14 | 11 | 3 |
| Mean time to recurrence, d (±SD) | 14.7 (±6.0) | 14.3 (±6.2) | 16.8 (±4.6) |
| P valuea | .040 | .044 | .497 |
Abbreviation: SD, standard deviation.
a t Test comparing mean time to recurrence between the vancomycin- and fidaxomicin-treated groups.
