Figure 1From: 1062 Echocardiographic assessment of semilunar valve incompetence useful as screening tool but unreliable in quantification: correlation with cardiac MR velocity mappingBoxploes of RF by ECHO grades of SVI. Box plots representing the inter-quartiles ranges (first to third quartile, Q1 to Q3), and a line ("whiskers") extending out a distance of 1.5 times the inter-quartile range below Q1 and above Q3. Values marked * represent the most exreme values within each group. The dot and horizontal line in each box represent the mean and median respectively. 1-Mild, 2 = Moderate, 3 = Severe.Back to article page
