Preconditions for analysis
To ensure that there was no carry-over effect due to the order of the interventions and that the first night in each week can be set as baseline, a Wilcoxon-Test was used to compare both baselines and a Mann–Whitney-U-Test was used to compare both order groups (participants starting with intervention R vs. participants starting with intervention F). No significant difference between baseline nights or order of intervention groups was found. An order-effect and a carry-over-effect can be rejected.All values and results of statistical analysis comparing nights can be read in Supplementary Table
