Insulin Resistance in Early Rheumatoid Arthritis Is Associated with Low Appendicular Lean Mass

Table 5

Summary of binary logistic regression analysis for variables predicting insulin resistance in the ERA Group.

	B	±SE	Sig.	exp(B)	95% CI for exp(B)
					Lower	Upper
Gender	2.0	0.80	0.01	7.35	1.55	34.91
ALMI	−3.45	1.74	0.05	0.03	0.001	0.97
TNF-alpha (pg/ml)	0.42	0.26	NS	1.52	0.91	2.53
DAS28 score			NS
High DAS28 score	1.82	0.65	0.005	6.19	1.72	22.2
Moderate DAS28 score	0.48	0.53	NS	1.62	0.57	4.59

Note. Gender is for males compared to females. ALMI: appendicular lean mass index (appendicular lean Kg/BMI); TNF-alpha: tumor necrosis factor-alpha; DAS28: disease activity score calculated using 28 joints. High and moderate DAS28 score compared to low score.
