MGM network plot of patient characteristics, consultation motives, ED consultation features and outcomes. Note. Green edges indicate positive, red edges negative associations. The ring around the SRW node visualizes predictability of SRW by the remaining network nodes: The orange part indicates the accuracy of the intercept (marginal) model and the red part shows the additional accuracy achieved by connected nodes. As the network graph is force-directed, graphical spacing of two connected nodes does not reliably represent the magnitude of their association, thus barring spatial interpretations [50]. Multi-categorical variables “migration and travel” and “education” were binarized to avoid unsigned edges. For migration, this meant categorization of participants not born in Germany (first-generation migrants and tourists) vs. others; Regarding education, dichotomization threshold was set between CASMIN categories for high education (=tertiary) vs. intermediate and lower education (=primary and secondary)
