anxiety
SECONDARY
The secondary analysis consists of the analysis of the global score values, and the comparison between the two study groups, of the patient questionnaires (with matching or adjustment for baseline anxiety values), the surgeons and the radiologists, using the Student’s t-test (/ non-parametric test) or the chi-square test (/ Fisher’s exact test), depending on the nature of the data. If a statistically significant difference between groups is found, a post-hoc analysis will follow on the questionnaire items, with multiple testing corrections.Data on localization quality will also be analysed and compared between groups using one-tailed tests to ensure that they do not indicate an inferiority of the experimental device.
