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
objectivesSleep experiences in later life are shaped by multiple biological, psychological, and social factors. This exploratory cross-sectional study examined associations between subjective sleep quality, daytime napping, dream recall, and selected health and psychosocial variables in community-dwelling older adults, within a biopsychosocial framework.
methodsA cross-sectional questionnaire-based survey was conducted in Greece among 609 community-dwelling adults aged 60 years and older. Participants completed self-report measures of health-related quality of life (SF-36), loneliness, humor styles, and brief single-item measures of subjective sleep quality, sleep sufficiency, daytime napping, and dream recall. Descriptive statistics, Spearman correlations, Mann-Whitney U tests, and multiple regression analyses were performed. Given the exploratory design and the use of multiple statistical tests without correction for multiple comparisons, the findings were interpreted cautiously.
resultsSleep quality was positively associated with mental health (ρ=0.247), physical health (ρ=0.211), and affiliative humor (ρ=0.148) and negatively associated with emotional loneliness (ρ=-0.215). Sleep sufficiency and sleep quality were almost perfectly correlated (ρ=0.989), suggesting substantial conceptual overlap. Daytime napping was positively associated with age (ρ=0.184) and was more frequent in men than women. Dream recall was positively associated with physical health (ρ=0.141) and self-enhancing humor (ρ=0.202) and negatively associated with social loneliness (ρ=-0.136). In multivariable analyses, mental health (β=0.145; p=0.049) and affiliative humor (β=0.159; p=0.001) were independently associated with sleep quality.
conclusionSubjective sleep experiences in older adults showed modest associations with health status, loneliness, and humor styles. These findings should be considered preliminary and exploratory, particularly because key sleep and dream variables were assessed using non-validated single-item measures, several associations were modest in magnitude, and multiple statistical tests were conducted without correction for multiple comparisons. The results may help generate hypotheses for future studies using validated multidimensional sleep and dream measures, but they should not be interpreted as confirmatory or causal evidence.
