† Forward stepwise (likelihood-ratio) multivariate
logistic regression
‡ Dichotomized total score according to the cut-off
value (<40 = 0; ≥40 = 1)
§ Independent variables entered into the model: gender
(man = 0, woman = 1), visit prior to MRI (No = 0, Yes = 1), telephone
call prior to MRI (No = 0, Yes = 1), sedatives prior to MRI (No = 0, Yes
= 1), relatives present in the MRI room (No = 0, Yes = 1), music during
MRI (No = 0, Yes = 1), referral diagnosis (malignancy = 1, other disease
= 0), high trait anxiety (STAI-T total score <40 = 0, STAI-T
total score ≥40 = 1), group affiliation (intervention group = 0, control
group = 1). Independent variables that are not presented in the table
were not significantly associated with experiencing high anxiety levels.
