Serum Neuropeptide Y Levels Are Associated with TNF-α Levels and Disease Activity in Rheumatoid Arthritis

Table 4

Factors associated with serum levels of NPY in rheumatoid arthritis (RA) in the multivariate multiple regression analysis.

		95% CI
Dependent variable: NPY levels
TNF-α (pg/mL)	0.023	0.006 to 0.039	0.008

Models using forward stepwise method. The model was adjusted by age, BMI, anti-CCP levels, TNF-α levels, leptin levels, fat mass (%), and RA disease duration.
