Serum level of adiponectin is a surrogate independent biomarker of radiographic disease progression in early rheumatoid arthritis: results from the ESPOIR cohort

Table 4 Association of baseline serum adipokine levels and rapid radiographic disease progression defined as an increase of ≥ 5 units in total SHS between inclusion and 1 year (total ∆SHS ≥5)

OR, odds ratio; 95% CI, 95% confidence interval.
Multivariate models:
Model 1 (“base”): sex + age.
Model 2 (“metabolic”): model 1 + BMI + HOMA-IR index.
Model 3 (“metabolic + RA”): model 2 + CRP level + DAS28-ESR value + HAQ score + RF status + anti-CCP antibody status + presence of radiographic changes at inclusion.
Model 4 (“metabolic + RA + steroid”): model 3 + steroid prescription at inclusion.
The following variables were log-transformed: CRP level, HAQ score, serum adipokine levels. Bold P values are significant.
