The COVID-19 syndemic: a perfect storm for the life expectancy of the most disadvantaged Americans.
Article in International journal of epidemiology, 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
backgroundTo explore the syndemic nature of the COVID-19 pandemic by identifying which subpopulations in the United States (US) suffered the greatest losses in life expectancy (LE) in 2020 and 2021, and to which extent these losses can be attributed to COVID-19 and 'other' causes of death.
methodsWe analysed individual death records for 2018-2021 from the National Vital Statistics System and population counts from the American Community Survey. Life table and continuous change decomposition analyses were used to quantify cause-/.specific contributions to changes in LE over time in population subgroups defined by sex, educational attainment, and race/ethnicity.
resultsFrom 2019 to 2020, educational differences in LE (high minus low education) increased substantially by 5.0 and 2.6 years in Hispanic men and women, respectively, with increases of one to two years among Black and White adults. Nearly all losses in LE among high-education Hispanic and White groups were due to COVID-19, while among low-education White and Black groups, COVID-19 accounted for 40%-47% of the total losses in LE. Changes in LE were much smaller during 2020-2021.
conclusionsCOVID-19 widened preexisting inequalities in LE in the US, both via direct mortality and through syndemic interactions with other diseases and health conditions. The underlying social, political, economic, and environmental factors driving the clustering and interaction of diseases among the most disadvantaged Americans need to be addressed.
