Comparing Pearson correlation coefficients between contact-enriched set and reference set defined by different thresholds ( c )

Thresholds for contact-enriched set	PCC (number of residues) on contact-enriched set	PCC (number of residues) on reference set
c ≥ 1	0.50 (4,447)	0.59 (4,078)
c ≥ 2	0.33 (1,981)	0.64 (6,544)
c ≥ 3	0.25 (671)	0.65 (7,854)

The first column stands for different thresholds, and the last two columns stand for Pearson correlation coefficients of transmembrane residues from the two different sets.
