Spearman (r_s) correlations between total protein measures originated from morning and evening saliva collected at day 1 (d₁) and day 3 (d₃) of the sampling period.

	Salivary total protein; evening (d1)	Salivary total protein; morning (d3)	Salivary total protein; evening (d3)
Salivary total protein; morning (d1)	rs = 0.45**	rs = 0.61***	rs = 0.39**
	n = 93	n = 94	n = 94
Salivary total protein; evening (d1)		rs = 0.38**	rs = 0.78***
		n = 93	n = 93
Salivary total protein; morning (d3)			rs = 0.37**
			n = 101
