Persistent Sleep Disturbance Following Pandemic Lockdowns: Longitudinal Findings From the UK COVID-19 Symptom Study Biobank.
Article in Journal of sleep research, 2026. 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
Sleep disturbance and fatigue were highly prevalent during the COVID-19 pandemic, in both infected and non-infected individuals, though mostly assessed cross-sectionally. To assess these symptoms after lockdown cessation, we conducted a prospective longitudinal study in a large UK cohort. Validated questionnaires assessing sleep disturbances, fatigue, depression, and anxiety were administered to COVID Symptom Study Biobank participants at two time periods-Autumn 2021 and Spring 2022 equinoxes-corresponding to lockdown and lifting of restrictions, respectively. After adjusting for differential participation using inverse probability weighting, data from 2390 participants were analysed. Generalised linear models examined SARS-CoV-2 infection, post-COVID-19 syndrome [PCS], and longitudinal changes of sleep disturbances and fatigue, adjusting for potential confounders. Despite lifting of lockdown, high levels of sleep disturbance and fatigue persisted, with no significant improvement over time, independently of baseline or new SARS-CoV-2 infection or PCS. De novo SARS-CoV-2 marginally worsened STOP-Bang scores although below clinical significance. There was a trend for interaction between baseline SARS-CoV-2 status and Chalder Fatigue scores on follow-up fatigue (B = 0.19, 95% CI = -0.01 to 0.39, p = 0.057). Receipt of booster vaccination lowered Epworth Sleepiness Scale scores (B = -0.53, 95% CI = -0.96 to -0.10, p = 0.016) but doubled likelihood of restless legs syndrome symptoms (OR = 2.45, 95% CI = 1.38 to 4.37, p = 0.002). Overall, the high rates of sleep disturbances and fatigue observed during lockdown persisted after restrictions were lifted, independent of SARS-CoV-2 infection. Sleep disruption reported during lockdown may endure unless actively addressed. Given the high prevalence of both sleep disturbance and fatigue, routine assessment of sleep is recommended for individuals presenting with persistent post-pandemic fatigue, including PCS.
