Fig. 4: Box Plots of observed, expected, and fitted values of the incidence of “Mental and behavioural disorders (F00-F99)”, 2018–2023.
From: Impact of the COVID-19 pandemic on incident diagnoses in German refugee centres 2018 to 2023

Cfactual: counterfactual (expected) values given the respective age- and sex-distribution of underlying refugee population (occupancy) in reception centres at given time points. Fitted: fitted values based on negative binomial regression models, adjusted for age, sex, centre characteristics, and secular trends. Observed: crude incidence proportions, i.e., cases of individuals with one or more new diagnoses defined by the indicator variable divided by the total number of refugee centre inhabitants (occupancy). Psych. condition: Mental and behavioural disorders. Cum. Incidence: Cumulative Incidence, occup.: occupancy. Y-axis: cumulative incidence in %. Boxes: interquartile range. Whiskers: Range. Horizontal black bar in boxes: Median. N = 836 centre-months. Source data are provided in the ‘source_data.xlsx’ file.
