By comparing our findings with previously reported blood lipid-associated CpGs in the general population from the EWAS Catalog, only four overlapping CpGs were identified among EA survivors, including cg00574958 (associated with TG and TC exposure), cg09737197 (associated with TG exposure), and cg17058475 (associated with TG and TC exposure) in CPT1A, and cg03725309 (associated with TG exposure) in SARS (Additional file 1: Tables S6 and S7), and none among AA survivors. Here, CPT1A is linked to severe acute respiratory syndrome.
