“…Of the parallel group trials, 20, 4, and 7 studied pulse wave velocity [ 13 , 16 , 26 , 39 , 40 , 41 , 42 , 43 , 46 , 47 , 49 , 52 , 53 , 54 , 55 , 56 , 58 , 59 , 60 , 62 ], augmentation index alone [ 23 , 48 , 57 , 63 ], and both [ 44 , 45 , 50 , 51 , 61 , 64 , 65 ], respectively (table 4 ). These trials included 20 comparisons of ACE inhibitors with ARBs (n = 6) [ 16 , 39 , 40 , 41 , 42 , 43 ], β-blockers (n = 2) [ 13 , 44 ], CCBs (n = 8) [ 13 , 39 , 40 , 43 , 44 , 45 , 46 ], and diuretics (n = 4) [ 44 , 47 , 48 , 49 ], 13 comparisons of ARBs with β-blockers (n = 2) [ 50 , 51 ], CCBs (n = 10) [ 39 , 40 , 43 , 52 , 53 , 54 , 55 , 56 , 57 , 58 ], or a diuretic (n = 1) [ 23 ], 5 comparisons of β-blockers with CCBs (n = 4) [ 13 , 26 , 44 , 59 ] or a diuretic (n = 1) [ 44 ...…”
