Enhancer enrichment analysis for five lead eQTL SNPs from COPD eQTLs with strongest colocalization signal (Table 2).
ID—ENCODE or Roadmap Epigenomic cell identification.
Obs, observed number of overlaps with enhancer regions; Exp, expected number of chance overlaps; Fold, fold enrichment over expected rate; P-value, calculated by binomial test compared with distance-matched (from transcription start site) controls (23).
