Table 8. The distribution of promoter usage in the SCs and the negative controls (NCs); CpG-richness and AP usage are considered.

Promoter type	Mean±Standard Deviation		P-value
	SC	NC
CpG-rich	91.56±5.37	77.62±7.30	0.001455
AP	22.83±9.92	24.32±4.00	0.5986

P-values calculated using the Welch two sample t-tests. The promoters are classified using the Baek et al (2007) scheme. The notes for Table 5 provide further explanations.
