Differences in organism recovery
| 2022 Mean (SD) | 2023 Mean (SD) | Mean Difference, % | P Value | |
|---|---|---|---|---|
| Total organisms | 0.25 (0.62) | 0.44 (0.88) | 55.07 | <0.0001 |
| Total aerobes | 0.01 (0.14) | 0.02 (0.098) | 66.67 | 0.0344 |
| Total facultative anaerobes | 0.071 (0.29) | 0.129 (0.39) | 58 | <0.0001 |
| Total obligate anaerobes | 0.16 (0.51) | 0.30 (0.76) | 60.87 | <0.0001 |
These data show the difference in recovery of organisms in anaerobic cultures between the 2022 and 2023 datasets. The culture differences were statistically evaluated using a Mann–Whitney U test, with all categories showing significant P values less than .05.
