(A) Up-regulated transcripts were 0 from GSE57691 and 284 from GSE7084. Down-regulated transcripts were 438 from 57691 and 208 from GSE7084. Twelve genes were significant in both cohorts. (B) Of these 12 genes, 3 were significant between intermediate size of AAA and large size of AAA in GSE 98278; 2 were significant between stable AAA and rupture AAA in GSE 98278. FRZB and C1orf24 were concomitantly significant. Abbreviations: eAAA, elective AAA; iAAA, intermediate AAA; lAAA, large AAA; rAAA, ruptured AAA.
