(A)NR2F2 median methylation level; (B)TBX5 median methylation level; (C)CFC1B median methylation level; (D)GJA5 median methylation level; TSS, Transcription Start Sites; red vertical line, CpG sites; red thick bars, CpG islands; The region between two arrows, target amplicon. *P < 0.05, **P < 0.01, ***P < 0.001 (Mann–Whitney test).
