Association between caregivers of dementia and sleep quality : A nationwide population-based study.

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
objectivesFinding the associations between cohabitation status and sleep quality in caregivers of people with dementia (PLwD) was the goal of this study.
methodsThis cross-sectional study included 230,900 adults who participated in the 2024 Korean Community Health Survey (KCHS). Sleep quality evaluated by the Pittsburgh Sleep Quality Index (PSQI) were compared between 3,709 cohabitating caregivers of PLwD, 21,080 non-cohabitating caregivers of PLwD, and 206,111 non-dementia caregivers. Multiple logistic regression were performed to evaluate the relationship between the cohabitation status caregivers of PLwD and sleep quality measured using the PSQI and PSQI subcomponents.
resultsCohabitating and non-cohabitating caregivers of PLwD group was significantly poor psychosocial variables (stress, depression assessed by Patient health questionnaire-9 (PHQ-9)) and higher prevalence of poor sleep quality (PSQI score ≥ 6). than non-dementia caregivers. Multivariable logistic regressions adjusted for potential confounders revealed that cohabitating caregivers of PLwD (odds ratio (OR) 1.17, 95% confidence interval (CI) 1.13-1.20) and non-cohabitating caregivers of PLwD (OR 1.12, CI 1.04-1.20) were significantly associated with poor sleep quality. In addition, PSQI subcomponents showed that sleep quality (OR, 1.16; 95% CI, 1.03-1.31), sleep latency (OR, 1.14; 95% CI, 1.06-1.22), sleep duration (OR, 1.11; 95% CI, 1.07-1.15), sleep efficiency (OR, 1.25; 95% CI, 1.12-1.39), sleep disturbance (OR, 1.13; 95% CI, 1.01-1.26), sleep medication use (OR, 1.61; 95% CI, 1.44-1.80) and daytime dysfunction (OR, 1.41; 95% CI, 1.32-1.51)) were associated with cohabitating caregivers of PLwD.
conclusionOur results showed that both cohabitating and non-cohabitating caregivers of PLwD experienced overall poorer sleep quality compared to non-dementia caregivers.
