Fig. 3 —Bar graph with SD error bars shows mean vessel scores by degree of
stenosis: mild-grade stenosis or normal (0-29%), n = 44;
moderate-grade stenosis (30-59%), n = 15; and high-grade stenosis
(60%), n = 43. Vessels with high- and moderate-grade stenosis had
significantly higher scores than those with mild-grade stenosis or normal
vessels (p < 0.005). There was no significant difference between
scores of high- and moderate-grade stenotic vessels (p = 0.82).
Asterisks indicate p < 0.05.
