Does COVID-19 Infection Continue to Affect Self-Reported and Objective Sleep? A Longitudinal Study of Good Sleepers.
Article in Nature and science of sleep, 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
Background: Whether COVID-19 infection continues to affect both self-reported and objective sleep is not clear. This longitudinal study aims to investigate the impact of COVID-19 infection on self-reported and objective sleep of good sleepers. Methods: Fifteen good sleepers, with prior COVID infection, completed self-reported and objective sleep assessments at 3 time points: pre-COVID-19 infection, short-term post-COVID-19 infection for 1 month and long-term post-COVID-19 infection for 6 months. Self-reported sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI). Self-reported sleep onset latency (s-SOL) and sleep efficiency (s-SE) were extracted from the PSQI. Objective sleep was assessed by overnight polysomnography. Nighttime electroencephalogram (EEG) relative power at central EEG derivations during sleep was calculated. Results: Total scores of the PSQI ( Conclusion: COVID-19 infection has temporary adverse effect on self-reported sleep but no effect on objective sleep of good sleepers.
