Impact of COVID-19 Infection on Quality of Sleep.

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
introductionSome studies have highlighted the effect of COVID-19 infection on the quality of sleep; however, the data is limited. In this study, we investigated the prevalence of insomnia in patients who recently recovered from the COVID-19 infection to evaluate the prevalence and extent of its impact.
methodsThis longitudinal study was conducted from January 2021 to March 2021. A total of 500 patients admitted to the intensive care unit or isolation unit of COVID-19 were included in the study at the time of their discharge. The pre-COVID-19 sleep quality of the participants was inquired using the Pittsburgh Sleep Quality Index (PSQI). Post-COVID sleep quality was assessed at a 30-day follow-up. Sleep quality was considered poor if the global score was ≥5. Participants that failed to follow up were not included in the study.
resultsThe mean PSQI score was significantly higher in the post-COVID-19 group compared to the pre-COVID-19 group (6.28 ± 2.11 vs. 3.22 ± 0.80; p-value <0.0001). The percentage of participants with a PSQI score of ≥5 was significantly higher in the post-COVID-19 group compared to the pre-COVID-19 group (45.1% vs. 12.1%; p-value <0.0001).
conclusionInsomnia has a significant prevalence in recovered COVID-19 patients after 30 days of follow-up. Hence, patients need to be counseled to follow up in case they experience poor sleep. To avoid the long-term negative impact on patients experiencing insomnia, timely identification and treatment are important.
