Smoking Functions as a Negative Regulator of IGF1 and Impairs Adipokine Network in Patients with Rheumatoid Arthritis

Figure 1

Serum levels of IGF1 and adipokines in RA patients grouped by smoking habits. Serum levels of IGF1 (a), leptin (b), resistin (d), adiponectin (c), visfatin (e), and BMI (f) in RA patients grouped by smoking habits in current smokers (Sm, ), former smokers (FSm, ), or never smokers (NSm, ). Boxes represent median and interquartile range. The comparison was performed by the Kruskal Wallis nonparametric ANOVA with Dunn’s multiple comparisons test.
