Clustering using atrium, PBL and PBL calibrated (SVM) methylation. (a) There are 14 samples: two female (white) and 12 male (red). The PostOpAF contains four cases (red) and 10 controls (white). The controls are grouped into two groups indicated by red circles and turquoise circles. One group contains sample #394, #286, #241, #271 and the other group includes #501, #274, #337, #397 and #412. (b) The two groups of controls indicated by red and turquoise circles are mixed together and one control (#271) is first clustered with two cases (#511, #177) and then with other controls (turquoise and red), and there are two controls (#501, #337) distinct from other controls. (c) The turquoise and red controls are now clustered back together, respectively, and locate at the bottom of the tree, except control #501 that was also close to case #215 using atrium methylation (a) and case #511 that is now clustered with the red group controls but was clustered with turquoise controls.
