Table 5. Ratios of median disease activity measures^* between RA patients with and without common comorbidities.

Comorbidity	n (%)	CRP	CDAI	DAS28-CRP	MBDA Score
Hypertension	223 (44)	0.98	1.32†	1.14†	1.05
Osteoarthritis‡	172 (34)	0.88	1.17	1.13	1.05
Osteoporotic bone fractures	131 (26)	0.91	1.05	1.02	1.05
Degenerative joint disease‡	113 (22)	1.20	1.18	1.11†	1.07
Diabetes	73 (14)	1.01	1.09	1.04	1.07†
Asthma	50 (10)	1.28	1.11	1.05	1.05

^*Values close to 1.0 indicate that the measurement or test is not affected by the comorbidity.

^†Nominal P<0.05 adjusted for age and sex; when adjusted for multiple comparisons, none was statistically significant.

^‡Osteoarthritis and degenerative joint disease were listed as separate conditions on the case report forms.
