PASSAGE
A research study examined the effectiveness of a new antihypertensive medication. The study followed 1,000 patients for 2 years. Group A (n=500) received the new medication, while Group B (n=500) received standard therapy. Results showed that 15% of patients in Group A experienced cardiovascular events compared to 25% in Group B. The relative risk was 0.6 (95% CI: 0.45-0.80, p<0.05). The number needed to treat (NNT) was calculated as 10.
What is the most appropriate interpretation of these study results regarding the clinical significance of the new medication?
