  1. Illumina probe IDs in bold indicate probes unique to the analysis at that time point
  2. aGene symbol and map position as Illumina manifest, GRCh37/hg19
  3. b‘Intergenic’, no gene loci annotation in Illumina manifest
  4. c P value in ‘traditional’ differential methylation analysis
  5. dIndicates ranking in combinatorial analysis if applicable. NA indicates that the CpG site was not seen in this analysis
