highly significantP = 0.003
Compared with lisinopril monotherapy, dual blockade treatment caused a highly significant reduction in 24-hour PP levels (−5 ± 5 mmHg, P = 0.003), albeit the difference in the BP lowering effect between the treatment groups did not differ significantly for 24-hour SBP ( P = 0.21) or DBP ( P = 0.49).
