Relationships between the TRACP-5b levels and the number of diseased vessels and the Gensini scores. (A) The differences in the TRACP-5b levels among the groups with one- (n = 12), two- (n = 30) and three-vessel (n = 29) disease. Higher TRACP-5b levels were significantly associated with an increased severity of CAD, as assessed by the number of diseased vessels (p = 0.018). (B) The differences in the TRACP-5b levels among the Gensini score quartiles (Q1, Q2, Q3, and Q4). Similarly, higher TRACP-5b levels were significantly associated with an increased extent of coronary atherosclerosis as estimated by the Gensini score (p = 0.038). The box and whisker plots show the median levels and the 25th and 75th interquartile ranges (delineated by the bottom and top of each box), and the circles represent outliers (> 1.5% of the 75% confidence interval).
