Fatigue, sleep quality and mental health symptoms in Brazilian women during the COVID-19 pandemic: longitudinal study.
Observational study in Scientific reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
To assess the impact of the COVID-19 pandemic on the variables of sleep quality, fatigue, anxiety, and depression in healthy Brazilian women. Longitudinal observational study conducted through an online questionnaire with women in 2020 and 2021. The Pittsburgh Sleep Quality Index, the Fatigue Severity Scale and the Hospital Anxiety and Depression Scale were used. The data were analyzed descriptively and the comparison between the data obtained in the first and second evaluation was performed using the McNemar test. A logistic regression was applied to test the association between the variables that showed a significant difference. A total of 235 women responded to the questionnaires. There was a significant increase in fatigue between the two moments (p < 0.05). In the first assessment, depression (OR: 2.39; 95% CI: 1.14-4.99), anxiety (OR: 2.68; 95% CI: 1.37-5.22) and sleep quality (OR: 4.01; 95% CI: 1.71-9.67) were associated with fatigue. In the second assessment, depression (OR: 2.93; 95% CI: 1.19-7.18) and anxiety (OR: 2.69; 95% CI: 1.27-5.71) were associated with fatigue. There was an impact on biopsychosocial aspects during the COVID-19 pandemic, with worsening of fatigue symptoms within a 6-month interval. In addition, fatigue was associated with symptoms of depression and anxiety, and worse sleep quality in the first year of the pandemic, remaining associated with symptoms of depression and anxiety in the second year of the pandemic in the country.
