Correlations between serum C-reactive protein (CRP), salivary CRP, and salivary CRP/total protein ratio calculated by Spearman’s (r_s).

	Salivary CRP; morning	Salivary CRP; morning (% of total protein)	Salivary CRP; evening	Salivary CRP; evening (% of total protein)
Serum CRP	rs = 0.19	rs = 0.20	rs = 0.27**	rs = 0.20*
	n = 99	n = 99	n = 97	n = 97
Serum CRP (≤3 mg/mL)	rs = 0.19	rs = 0.20	rs = 0.28**	rs = 0.20*
	n = 80	n = 80	n = 79	n = 79
Serum CRP (>3 mg/mL)	rs = 0.25	rs = 0.14	rs = 0.54*	rs = 0.36
	n = 19	n = 19	n = 18	n = 18

Values are shown for all samples as well as for the low and high serum CRP levels (≤3 mg/ml, >3 mg/L).
