A: The proportion of patients improving by at least 2 CCS angina grades, and by at least 1 CCS angina grade, was significantly higher among Reducer patients compared to control (34.6% vs. 15.3% for at least 2 CCS angina grades, p=0.02; and 71.1% vs 42.3% for at least 1 CCS angina grade, p = 0.003).

B: Mean CCS angina class was reduced from 3.19±0.4 at baseline to 2.13±0.97 at 6-month follow up in the Reducer group, and from 3.13±0.34 to 2.65±0.88 in the sham control group. The improvement was significantly better in the Reducer group (p=0.001).
