A systematic review to understand the long-term mental health effects of influenza pandemics.
Synthesis in Scandinavian journal of public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
aimsHealth effects of pandemics extend beyond morbidity and mortality from the disease itself and may include long-term mental health consequences. However, previous studies only consider narrowly defined populations at risk or examine pandemics caused by varied pathogens that may have inconsistent effects. We examine existing literature on these long-term mental health effects following one type of pandemic (influenza).
methodsWe conducted a systematic review of the long-term mental health effects of the 1889, 1918, 1957, 1968, and 2009 influenza pandemics. To our knowledge, this is the first review of studies of broad populations and multiple measures of mental health morbidity.
resultsThe literature search returned 8190 articles. After deduplication and title/abstract and full-text screening, 12 articles were reviewed. Seven articles focused on the 1918 pandemic and five on the 2009 pandemic. Study regions were USA or North America (
conclusionsMental health effects have been an outcome of pandemics. Researchers should consider a variety of possible mechanisms, and that infection and restrictive NPIs may contribute to mental health morbidity. This study highlights the need for better understanding of the broader health, social, and demographic impacts of pandemics.
