Longitudinal relationship between ASDAS and radiographic damage in different strata
| Stratification for | Multivariable regression models |
|---|---|
| (auto-regressive and time-lagged) | |
| Effect analyzed | β (95%CI)* |
| Smoking status | |
| ASDAS in non-smokers (n=78) | 0.35 (0.04; 0.65) |
| ASDAS in smokers (n=49) | 1.94 (1.00; 2.87) |
| Smoking status & gender | |
| ASDAS in women, non-smokers (n=29) | 0.16 (−.13; 0.44) |
| ASDAS in women, smokers (n=9) | 0.47 (−0.12; 1.06) |
| ASDAS in men, non-smokers (n=49) | 0.44 (0.02; 0.86) |
| ASDAS in men, smokers (n=40) | 2.15 (1.01; 3.30) |
| Smoking status & symptom duration | |
| ASDAS in symptom duration <18y, non-smokers (n=39) | 0.52 (0.24; 0.80) |
| ASDAS in symptom duration <18y, smokers (n=31) | 2.11 (0.86; 3.36) |
| ASDAS in symptom duration ≥18y, non-smokers (n=35) | 0.26 (−0.18; 0.70) |
| ASDAS in symptom duration ≥18y, smokers (n=13) | 0.88 (0.15; 1.62) |
↵* Results refer to different multivariable models. The β indicates the progression in mSASSS per unit increase in ASDAS.
