Although the univariate analysis showed that professional status (univariate OR = 1.77; 95% CI: 1.16–2.71), going to work with a self-owned car (univariate OR = 1.44; 95% CI: 1.04–2.00) and private insurance (univariate OR = 1.51; 95% CI: 1.00–2.27) were associated with perception of CUP as beneficial, at the multivariate analysis, those associations lost significance; regarding professional status, only a marginal trend remained ( p = 0.065).
