Lockdown COVID‑19: a stress test revealing more about the mental health system than psychopathology-A comparative analysis between Austria, Germany, and Italy.
Observational study in Frontiers in public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: This study examined whether the COVID-19 pandemic produced diagnosis-specific and cross-nationally reproducible alterations in psychiatric admissions, or whether observed variations primarily reflected organizational responses. We compared psychiatric inpatient services from Austria and Germany-two hospital-centered systems with similar pre-pandemic structures-and used Italy as a contrasting community-based model. Methods: We conducted a retrospective multicenter observational study including all psychiatric hospitalizations between 2017 and 2020. Temporal admission trends were analyzed bi-weekly for each ICD-10 diagnostic group. Generalized Linear Models (Poisson family) were used to model the effects of Diagnosis, Year (2020 vs. pre-2020), Week, and Country, and their interactions. Diagnostic categories were grouped following ICD-10, with F10 (alcohol-related disorders) analyzed separately from other substance-use disorders to capture differences between planned and emergency admissions. Results: Across Austria and Germany, 2020 was associated with a marked temporal distortion in admission patterns compared with previous years (Week × Year interaction, Conclusion: The pandemic did not induce diagnosis-specific increases in acute psychiatric admissions but substantially altered their temporal organization. Differences across countries highlight how healthcare structure-particularly the integration of territorial and inpatient services-modulates system resilience under crisis conditions.
