Table showing linear regression analysis of serum and salivary creatinine for controls and CKD patients.

Group	Linear regression equation	Sig.	𝑅^2
Control	𝑌 = 0.998 + (−0.913) × (Salivary Cr)	0.049	0.106
Cases	𝑌 = 2.924 + (4.595) × (Salivary Cr)	<0.001	0.534
Combined population	𝑌 = 1.846 + (5.748) × (Salivary Cr)	<0.001	0.643
