Hazard ratios for RA according to adiponectin and CRP levels

	Unadjusted HR (95% CI)	Model 1* HR (95% CI)	Model 2** HR (95% CI)
Adiponectin and CRP ≤median	1.00 (reference)	1.00 (reference)	1.00 (reference)
Adiponectin >median-CRP ≤median	2.26 (1.04–4.91)	2.19 (0.99–4.88)	2.03 (0.91–4.55)
Adiponectin ≤median-CRP >median	2.38 (1.10–5.17)	2.25 (1.01–5.02)	2.15 (0.95–4.87)
Adiponectin and CRP >median	3.39 (1.60–7.16)	3.20 (1.44–7.08)	2.80 (1.25–6.31)

^*In Model 1, HR are adjusted for age, sex, and BMI

^**In Model 2, HR are adjusted for age, sex, BMI, treatment (surgery yes/no), current or former smoking, ESR, diabetes and year of inclusion in the study.

CRP, C-reactive protein; HR, hazard ratio; CI, confidence interval; BMI, body-mass index.
