This implies the % of participants with total eradication is potentially higher than 76%.

Rationale:

1. Treatment stopped at day 5
2. Testing was conducted at day 7
3. 76% showed total eradication at day 7
4. Testing was conducted at day 28
5. 25% still showed total eradication at day 28
6. Between day 7 and day 28 the number of participants showing total eradication declined steadily
7. Presumably between day 5 (treatment stopping) and day 7 (testing) the number of participants showing total eradication also declined

We know from the preclinical work that BTX1801 kills bacteria within twenty minutes so shortly after treatment stopping is likely when the bacteria start reappearing.

Therefore, had participants been tested at day 5 (or day 6) the number of participants showing total eradication would most likely be above 76% because they are already into day 2 of the gradual decline that takes place between day 7 and day 28.

Assuming a linear decline (no idea if this is accurate but at least it's a simple approximation) between day 7 and day 28 the number of participants showing total eradication declined from 76% to 25% so if you project that trend in the opposite direction from day 7 to day 5 you actually get 81% showing total eradication, which is even better than the headline number.
