Age- and sex-adjusted comparisons between Hispanics and non-Hispanic Whites in RA characteristics over time in 706 RA patients^*

Characteristic	Coefficient or OR*	P-value
Tender joint count (range 0 – 46)	4.9 (3.2, 6.6)§	≤ 0.001
Swollen joint count (range 0 – 37)	0.49 (−0.15, 1.1)§	0.1
Deformed joint count (range 0 – 48)	5.0 (3.1, 6.8)§	≤ 0.001
ESR mm/Hr (range 0 – 141)	12.2 (8.9, 15.6)§	≤ 0.001
Sharp score** (range 0 – 314)	21.7 (10.6, 32.7)§	≤ 0.001
Subcutaneous nodules (no=0, yes= 1)	1.1 (0.8, 1.5)¶	0.1
Prednisone use (no=0, yes=1)	1.1 (0.9, 1.4)¶	0.2
Rheumatoid factor (no=0, yes=1)	1.3 (0.9, 1.8)¶	0.1
Charlson Comorbidity Index (range 1 – 12)	−0.04 (−0.25, 0.17)§	0.7

^*Values represent either the regression coefficient (§) or odds ratio (OR) (¶) with 95% CI from GEE regression models in which the clinical characteristic was the dependent variable. In these models, Hispanic=1, NHW=0. Thus, a positive coefficient or an OR >1.0 signifies greater mean or prevalence in the Hispanic patients.

^**There were 49 patients for which no x-ray radiograph was obtained. Therefore, the values shown are for a sample of 657 patients—252 Non-Hispanic Whites and 405 Hispanics—with 2,713 observations.
