Rheumatoid arthritis v control odds ratio for arterial obstruction or incompressibility, adjusting for the effect of potential confounding variables
| Model covariates* | Incompressibility | Obstruction | ||
|---|---|---|---|---|
| RA v controls OR (95% CI) | p Value | RA v controls OR (95% CI) | p Value | |
| *A series of multinomial logistic regression models was tested, all of which included rheumatoid arthritis vs. controls status as an independent variable, in addition to the listed covariates. | ||||
| BMI, body mass index (kg/m2); CI, confidence interval; CRP, C reactive protein; ESR, erythrocyte sedimentation rate; OR, odds ratio; RA, rheumatoid arthritis; SBP, systolic blood pressure. | ||||
