Table 2 Regression parameters for determination of repaglinide by the proposed method

Analyte	Linear regression					LDR (ng/mL)	LOD (ng/mL)	EF
Analyte	Slope	SE of slope	intercept	SE of intercept	r value	LDR (ng/mL)	LOD (ng/mL)	EF
Repaglinide	0.0370	0.0009	0.1436	0.0571	0.9969	1–100	0.4	480

SE: standard error; r: correlation coefficient; LDR: linear dynamic range; EF: enrichment factor
