When we compared top CpG sites from the initial cohort (EOD1) of general inpatients with and without delirium [11], we found significant overlaps in the samples obtained from additional inpatient cohort (EOD2), such as LDLRAD4, DAPK1, TLN2, and IRF8 shown in Table 2. The gene discussed is DAPK1; the disease is delirium.
