From the table at the bottom of the Abstract, we see that the mean CFU drops from 15.71 to 2.92 as a result of the Ultra-V process. This is a 5 fold reduction. Hygiene Solutions website promises a log4 to log6 efficacy for Ultra-V, i.e. a 10,000 fold to 1,000,000 fold reduction. How do Hygiene Solutions account for the difference?
From “Results” we see that only 25% of the rooms had a statistically significant reduction in CFU. How do Hygiene Solutions explain the 75% of rooms that had no significant reduction in CFU?
