Multiple stepwise regression analysis of resistin (dependent variable) and demographic and disease-related variables (independent variables)

	Resistin (ng/mL)
	11.155
	β	SE	P value
Erythrocyte sedimentation rate, mm/hour	0.044	0.012	0.001
S-creatinine, μmol/L	0.035	0.008	<0.001
Complement factor C3, g/L	-2.915	1.023	0.005
Glucocorticosteroid current dose, mg/day	0.127	0.051	0.014
High-density lipoprotein, mmol/L	-1.438	0.580	0.014
Bone mineral density radius, g/cm2	-7.133	3.156	0.026
R2	0.42

The regression equation of resistin (ng/mL) = 11.155 + 0.044 × erythrocyte sedimentation rate (mm/hour) + 0.035 × S-creatinine (μmol/L) - 2.915 × C3 (g/L) + 0.127 × current steroid dose (mg/day) - 1.438 × high-density lipoprotein (mmol/L) - 7.133 × bone mineral density radius (g/cm²). Beta values are unstandardized regression coefficients. R² is equal to the variance explained in the model. SE, standard error.
