Protective Effect of Costus afer Aqueous Leaf Extract (CALE) on Low-Dose Heavy Metal Mixture-Induced Alterations in Serum Lipid Profile and Hematological Parameters of Male Wistar Albino Rats

Table 6

Model equations for serum lipid profile parameters.

Parameters	Model type	Model equations	R^2	MSE	RMSE
HDL	Linear	y = 0.000x + 0.328	0.978	0.001	0.023
LDL	Polynomial (2^nd order)	y = 2E − 07x^2 − 0.000x + 2.411	0.998	0.001	0.038
TG	Linear	y = −0.000x + 2.149	0.990	0.006	0.079

y = concentration of the parameter analyzed, x = Costus afer dose, HDL = high-density lipoprotein, LDL = low-density lipoprotein, and TG = triglyceride, MSE = mean squared error, and RMSE = root mean squared error.
