Changes to the supervision done (a) online (e.g. via Zoom, FaceTime, Skype), (b) in person, (c) via email messages or (d) via phone. Shown is the number of total participants, the number of responses and distributions (in %) in each group, as well as p-values determined by comparison between groups 1 vs. 2. Significant differences in responses between groups 1 and 2 and specific subgroups were calculated using Fisher’s exact test
