Multivariate regression analysis between change in serum IL-6 concentrations and other variables
| Model number | Beta | 95% CI Beta | P value |
|---|---|---|---|
| Model 1 | |||
| Change in calcium-phosphate product | 0.35 | 0.13, 0.70 | 0.004 |
| Age | −0.35 | −0.57, −0.08 | 0.004 |
| Dialysis vintage | −0.14 | −0.30, 0.17 | 0.22 |
| Independent variables: age, gender, dialysis vintage, and changes in serum calcium, phosphate, calcium-phosphate product, and parathyroid hormone. | |||
| Model 2 | Beta | 95% CI Beta | P value |
| Change in serum endotoxin levels | 0.43 | 0.03, 0.87 | 0.0002 |
| Age | −0.30 | −0.42, −0.03 | 0.008 |
| Change in calcium-phosphate product | 0.24 | 0.02, 0.51 | 0.02 |
| Dialysis vintage | −0.14 | −0.32, 0.06 | 0.18 |
| Independent variables: Similar to model 1 + change in serum endotoxin levels. | |||
