Sleep patterns during the pandemic and covid-related stress: a large-scale study in the general population of Serbia and Republic of Srpska (Bosnia and Herzegovina).
Article in Population health metrics, 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
backgroundDuring the COVID-19 pandemic many people experienced psycho-social stress which affected their sleep. This study was conducted during the third and fourth epidemic wave when international borders of Serbia and Bosnia-Herzegovina were entirely open, no curfew or wearing face masks were imposed, but the highest rates of COVID-19-related fatalities were reported. The aim of this study was to examine sleep patterns with COVID-related stress during the pandemic.
methodsAnonymous paper questionnaires were distributed from September 2020 to October 2021 across 8 cities in Serbia and Republic of Srpska (Bosnia and Herzegovina). Socio-epidemiologic characteristics, the COVID Stress Scales-CSS and the Perceived Stress Scale were administered. Sleeping patterns before and during the COVID-19 pandemic (bedtime, time spent sleeping and sleep quality) were recorded.
resultsResponses of 2,301 participants suggested that bedtime after midnight before and during the pandemic did not differ (13.4% vs. 14.8%, respectively). Most participants reported similar length of sleep before and during the pandemic (around 7 h), although 11% of them reported that during the pandemic they slept more often compared to pre-pandemic sleeping schedule. There was an increase in prevalence of poor sleep quality during the pandemic (4.5% vs. 9.4%, respectively). Sleeping more often compared to pre-pandemic sleeping schedule and poor sleep quality during the pandemic were independently associated with a higher CSS.
conclusionProportion of people who reported poor sleep quality doubled in the pandemic. Optimizing sleep quality in crises among people who experience poor sleep quality should be prioritized when managing public health emergencies.
