1 · What the graph read from it

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.

2 · The registry

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

backgroundLoneliness is increasingly recognized as a global public health concern linked to adverse mental health outcomes. However, cross-national evidence on its distribution and association with depression and generalized anxiety is limited.

methodsWe analyzed data from the 2023-2024 Global Social Determinants of Health Survey, a cross-sectional, nationally representative survey of 7,997 adults across Brazil, France, India, Indonesia, Nigeria, the Philippines, Türkiye, and the United States. Depression and generalized anxiety were measured using PHQ-9 and GAD-7 screening tools, respectively, while loneliness was self-reported. Weighted bivariate and multivariate (logistic and Poisson regression) models were used to estimate associations between loneliness and mental health outcomes, adjusting for demographic factors.

findingsOverall, 38.9% of respondents reported loneliness, 9.2% met criteria for depression, and 5.5% for generalized anxiety. Loneliness was more common among younger adults, women, individuals with lower income or education, unmarried individuals, and urban residents. In fully adjusted models, loneliness was associated with depression (OR 2.82 [95% CI: 2.25-3.54]) and generalized anxiety (OR 3.89 [95% CI 2.86-5.28]).

interpretationLoneliness is common and strongly associated with depression and generalized anxiety across diverse settings. These findings underscore the importance of integrating strategies that promote social connection into mental health policy and interventions. Future research should explore causal pathways.
