Final answer:
The result is a statistically significant difference in blood pressure in the group of patients, despite the small difference in real numbers.
Step-by-step explanation:
The result is a statistically significant difference in blood pressure in the group of patients. Although the actual difference in terms of real numbers is only 1 mm Hg, it is still considered statistically significant with a p-value less than 0.05. This means that the difference is unlikely to have occurred by chance and is likely to be a true effect.
