Table 4.

Spearman (r_s) correlations between serum C-reactive protein (CRP), salivary CRP, BMI and plasma IL-6. 

	Serum CRP	Salivary CRP; morning	Salivary CRP; evening
BMI	rs = 0.43**	rs = 0.06	rs = 0.15
	n = 96	n = 99	n = 97
IL-6	rs = 0.41**	rs = −0.04	rs = 0.06
	n = 97	n = 98	n = 96
IL-6#	rs = 0.10	rs = 0.23	rs = 0.22
	n = 35	n = 35	n = 35

Subjects with undetectable IL-6 levels were given half the detection limit’s value. Additionally, correlations were calculated only for participants with detectable IL-6.

^#IL-6 above detection limit.

**p < 0.01.
