Stepwise Cox proportional hazards model showing independent predictors of mortality in patients with established rheumatoid arthritis
| Step and variable | Regression coefficient | Hazard ratio (95% CI) | p Value |
|---|---|---|---|
| *The TGFβ1 genotypes were ordered as categorical variables according to T allele number (that is, 0, 1, 2). The hazard ratio shows the increased risk per unit increase in T allele number. | |||
| CI, confidence interval; ESR, erythrocyte sedimentation rate; MAUC, mean area under the curve. | |||
| 1. MAUC ESR | 0.026 | 1.03/mm/h (1.01 to 1.04) | <0.0001 |
| 2. Age | 0.055 | 1.06/year (1.02 to 1.09) | 0.007 |
| 3. Male sex | 0.777 | 2.2 (1.2 to 4.1) | 0.003 |
| 4. TGFβ1 genotype* | 0.463 | 1.6 (1.02 to 2.5) | 0.04 |
