Multiple linear regression analysis of the association between serum UA concentration and lumbar spine bone mineral density.

Model	β	SE	p	Adjusted R²
Model 1	0.265	0.012	0.001	0.091
Model 2	0.176	0.010	0.014	0.287
Model 3	0.144	0.010	0.042	0.322
Model 4	0.185	0.011	0.014	0.310

Model 1 included serum UA and age. Model 2 included serum UA, age, and BMI. Model 3 included serum UA, age, BMI, and ESR. Model 4 included serum UA, age, BMI, ESR, and calcium. UA: uric acid; β: standardized beta coefficients. SE: standard error; BMI: body mass index; ESR: erythrocyte sedimentation rate.
