A 48 month study compared two treatments for hypertension in patients over the age of 60.
The null hypothesis was that there was no difference between the two treatments.
The primary outcome was reduction of systolic blood pressure below 140 mmHg. This outcome was reached in 75% of patients taking treatment A and 80% of patients taking treatment B. The results were reported as being significant with a p-value of 0.05.
What is the correct interpretation of the P value?
