84 Figure 5.1. Tukey box–and–whisker plots showing the distribution of the time between two assessments in days. The time between T0 (intake or clinical admission) and T1 (after 6 weeks of clinical admission) ranged from 16 to 394 days (left panel), and the time between T1 (after 6 weeks of clinical admission) and T2 (clinical discharge) ranged from 5 to 645 days (right panel). The box plots indicate the interquartile range and median; the whiskers indicate the minimum and maximum values, excluding the outliers which are represented by the white circles. Analyses The first author thoroughly checked all scores of the MoCA and corrected scoring errors of the assessor when needed. Ambiguities in the scoring for which the instructions on www. mocatest.org were not fully specified were scored or corrected in a consistent manner according to strict criteria (similar to the instructions for the newly released MoCA version 8.1 which was not yet available in Dutch at the time of data collection). The procedure of checking scores of all items by the same assessor eliminated inter–rater differences that were previously found to influence results (Cumming et al., 2020). First, characteristics of the patient sample as a whole are presented, as well as for all three groups. Differences in patient characteristics between groups were explored using univariate ANOVAs for scaled variables and chi–square tests for categorical variables.
