Psychological outcomes of depression after legally enforced quarantine during the COVID-19 pandemic: a cross-sectional study.
Article in BMC public health, 2025. 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
backgroundLegally enforced quarantines during the COVID-19 pandemic resulted in increased psychological distress, particularly among individuals with pre-existing mental health conditions. In this study, part of the Cologne Corona Counselling and Support for Infected and Contact Persons During the Quarantine Period (CoCo-Fakt) project, we hypothesised that individuals with pre-existing depression experienced greater psychological distress during legally imposed quarantine/isolation and thus require additional support. We also aimed to explore whether coping mechanisms and resilience can enhance the care provided to at-risk individuals facing similar situations.
methodsThis study included 10,033 participants (infected and contact persons) registered with the Cologne Public Health Department between December 2020 and January 2021. We collected data via online questionnaires covering demographics, mental health status, coping strategies, resilience, and support system usage.
resultsIndividuals suffering from depression (ISFDs, n = 260) reported significantly higher psychological distress scores than individuals not suffering from depression (INSFDs, n = 9773; p < 0.001). ISFDs also reported significantly lower coping (p < 0.001) and resilience (p < 0.001) scores and used support systems approximately six times more often. Backwards elimination regression analysis revealed significantly higher psychological distress scores among individuals who were female, were younger, had higher educational level, had COVID-19, and had a chronic disease other than depression. No significant interactions were found in the moderation analyses. The model accounted for 31.2% of the observed variance.
conclusionsThe findings suggest the need for tailored interventions to help both ISFDs and INSFDs develop coping strategies and resilience during quarantines. Ensuring that sufficient therapeutic services and support are available for ISFDs is crucial for maintaining good mental health.
