The gene expression levels as measured by the relative quantification method for our study genes are enumerated in Table 2. Gene expression levels are relative to GAPDH expression where GAPDH expression level is equal to 1.
The methylation status and expression levels with respect to the study genes are enumerated in Table 3. TNF methylation was examined at the promoter region and the first exon.
For consistency with the UK study, previous admissions were enumerated for three time intervals preceding the trigger admission – 90 days, one year and three years – for two admission categories: any admission and any emergency admission.
