Multivariable stepwise linear regression analysis of log-age, height, body weight, body mass index, waist circumference, diastolic blood pressure, HDL-C, log-triglyceride, log-insulin and log-HOMA-IR: correlation to fasting serum adiponectin level among 150 diabetic patients

Items	Beta	Adjusted R square	Adjusted R square change	P value
Log-insulin (uIU/ml)	-0.240	0.082	0.082	0.002*
Log-age (year)	0.289	0.151	0.069	< 0.001*
HDL-C (mg/dl)	0.211	0.188	0.037	0.006*

^* P < 0.05 was considered statistically significant after multivariable stepwise linear regression analyses.

HDL-cholesterol, high-density lipoprotein cholesterol; HOMA-IR, homeostasis model assessment of insulin resistance.
