Comparison of DKK1 concentration according to the type of coronary atherosclerotic plaque. DKK1 was significantly elevated in patients with both calcium-containing and non-calcified coronary atherosclerotic plaques compared to the patients without plaque. The central line represents distribution median, the boxes span from 25th to 75th percentiles, and the error bars extend from 10th to 90th percentiles. An outliers (open circles) are defined as a score that is between 1.5 and 3 box lengths away from the upper edge of the box. An extreme scores (asterisks) are defined as a score that is greater than 3 box lengths away from the upper edge of the box.
