Figure 4

Clinical performance evaluation of the angiographies. (a) Shows the clinical rating of participants’ performance of the passage of the pigtail catheter into the aortic arch in test session 1–3. On day 3, 95% of all trials completed by all participants of the pigtail catheter placement were rated with maximal performance (“totally acceptable”). (b) Shows the clinical rating of participants’ performance of accessing the ACC/ICA in test session 1–3. On day 3, 17% of all trials of the catheter placement into the carotid artery were still rated with “unacceptable and totally unacceptable”. Likert scale rating 1 = totally unacceptable, 5 = perfectly acceptable. Both figures show all individual trials completed by all participant during the three test sessions. Data points were jittered for improved clarity. This figure was created using the R software package²⁷.
