Comparison of indexed plaque volume components stratified by tertiles of systolic and diastolic blood pressure

Systolic blood pressure tertiles
Plaque type a 1st Tertile (≤ 118 mmHg) Median [IQR] 2nd Tertile (119–130 mmHg) Median [IQR] 3rd Tertile (> 130 mmHg) Median [IQR] p value for trend
Fatty 9.3 [5.3,13.7] 8.8 [4.8, 14.0] 9.2 [4.9, 14.3] 0.812
Fibrous 16.5 [9.4, 24.3] 15.1 [8.3, 23.6] 17.1 [9.6, 24.8] 0.758
Noncalcified 25.4 [15.0, 35.9] 23.7 [13.6, 37.5] 26.9 [14.3, 38.9] 0.775
Calcified 4.6 [2.1, 6.8] 3.9 [1.0, 8.8] 4.2 [2.0, 8.6] 0.690
Total 30.0 [18.1, 43.8] 29.3 [15.1, 45.8] 30.9 [17.9, 46.0] 0.645
Diastolic blood pressure tertiles
Plaque type a 1st Tertile (≤ 68 mmHg) Median [IQR] 2nd Tertile (69–76 mmHg) Median [IQR] 3rd Tertile (> 76 mmHg) Median [IQR] p value for trend
