Fig. 9

This decision tree shows decision pathways that lead to high frequencies of changing participants (blue nodes) and non-changing participants (green nodes). Every node presents an overall trend in the first line of the box (0: majority does not change/1: majority does change in this node), a percentage of the proportions of each category, and in the last line a percentage value about how many cases are included in this category from the overall sample of 4613 participants. Conditions are shown below the node separating the previous node into two smaller nodes consisting of cases separated by the condition. If the condition is fulfilled the pathway continues left, if the condition is not fulfilled the pathway continues right.
