Table 2. Correlation of various variables of diabetes with apelin levels.

Spearman's correlation was used to determine the significance.

FBS: fasting blood sugar; PPBS: postprandial blood sugar; HOMA-IR: homeostatic model assessment for insulin resistance

Parameters	Apelin (ng/mL)	p-value
HbA1c (%)	Correlation Coefficient (rho) = -0.05	0.09
FBS (mg/dL)	Correlation Coefficient (rho) = 0.29	0.027
PPBS (mg/dL)	Correlation Coefficient (rho) = 0.21	0.101
Fasting Insulin (µU/mL)	Correlation Coefficient (r) = 0.42	<0.001
HOMA-IR	Correlation Coefficient (rho) = 0.51	<0.001
