Early changes in bone mineral density measured by digital X-ray radiogrammetry predict up to 20 years radiological outcome in rheumatoid arthritis

Table 2 Impact of high early DXR-BMD loss and baseline demographic and disease characteristics on Larsen score at year 10 (linear regression model)^a

Patient demographics and disease characteristics	B	P_value
Early bone loss above median (yes/no)	16.572	0.037
Sex	3.573	0.620
Age	-0.462	0.134
ESR	0.540	0.000
Larsen score at baseline, 0 to 200	0.807	0.068
ACPA (yes or no)	-1.371	0.862

^a B, the estimated regression coefficient; ESR, erythrocyte sedimentation rate; ACPA, anticitrullinated peptide antibodies; high early DXR-BMD loss is defined as bone loss above median value.
