| Parameter | Valuea
for CRE in the case that Verigene results were: |
|

| Available (n = 8) | Absent (n = 7) | |
| Median days of inpatient treatment (IQR) | 7.5 (5.2, 12.5) | 7.4 (5.3, 14.3) |
| Patients who received effective treatment | 7 (87.5) | 7 (100) |

Unless otherwise noted, data are presented as number (percent).
Evaluated among patients who received effective therapy in each group: n = 7 for for the group with Verigene results available and n = 7 for the group for which Verigene results were absent.
Evaluated among patients who had potential benefit to reduce time to effective therapy by using Accelerate system’s results, compared to traditional culture results in each group: n = 2 for for the group with Verigene results available and n = 6 for the group for which Verigene results were absent.
Evaluated among patients who received definitive therapy in each group: n = 8 for for the group with Verigene results available and n = 7 for the group for which Verigene results were absent.
Evaluated among patients who had potential benefit to reduce time to definitive therapy by using Accelerate system’s results, compared to traditional culture results, in each group: n = 2 for for the group with Verigene results available and n = 6 for the group for which Verigene results were absent.
