Association between systemic lupus erythematosus (SLE) status and joint laxity according to age
| Unadjusted | Adjusted by sex* | |||
|---|---|---|---|---|
| Age group | Odds ratio (95% CI) | p Value | Odds ratio (95% CI) | p Value |
| The p value is that for the method used for testing the hypothesis that the value of the underlying odds ratio is equal to one. | ||||
| *The multiple logistic model was −2.45+1.92 (female) − 2.50 (age ≥49 years) + 0.84 (SLE) + 2.05 (age ≥49 years×SLE). The p value of the interaction term was 0.0029. Goodness of fit statistic=0.0381 with 1df (p=0.845). Area under the ROC curve: 0.81. | ||||
