  1. Results from Difference-in-differences models, estimated separately by migrant background. Coefficients and confidence intervals are scaled to the pre-lockdown level in the main sample (see Table 1). The outcome is the monthly propensity of having at least one consultation of the given type. Diagnoses are based on ICD-10 codes Chapter F (see Table 2). For the comparison sample, all measurements are taken 24 months earlier. Models control for duration in years, sex, municipality, month, age category and easter holiday. Bold is added to emphasize statistically significant estimates (p < 0.05)
