Table 2. Variables associated with active role preference on the eCPS among 87 people with MS in univariate and multivariate models. Age was categorized into two classes, with median as cutoff.

OR is odds ratio, and 95% CI the OR confidence interval, estimated by unconditional logistic-regression.
Multivariate model including all explanatory variables, with Hosmer-Lemshow goodness-of-fit test χ2 = 7.7 (degrees of freedom = 22), p = 0.47.
