Results showed: mean reduction of 8.2 mmHg in the treatment group vs. 2.1 mmHg in placebo group (difference = 6.1 mmHg, 95% CI: 4.8-7.4 mmHg, p = 0.001). The researchers noted that clinical guidelines consider a reduction of ≥10 mmHg clinically meaningful for cardiovascular risk reduction. Which statement best characterizes these findings?
