Risk for rheumatoid arthritis associated with abdominal obesity, defined as waist circumference >102 cm, in women

	Women
	OR (95% CI)
All	2.28 (1.15, 4.55)
Divided by the serostatus of the case after RA diagnosis:
Seropositive RA	2.54 (1.18, 5.47)
Seronegative RA	1.44 (0.29, 7.16)

Sensitivity analyses of the associations between abdominal obesity in women (n = 95 cases, and 279 controls), using the same cutoff as in men (waist circumference >102 cm), and risk of onset of rheumatoid arthritis (RA). Analysed overall and divided by serological status for rheumatoid factor and/or anti-citrullinated peptide antibodies for the case after RA diagnosis, respectively. Results from conditional logistic regression analyses adjusted for education and smoking, in case–control sets matched for age, year of examination and cohort
