The association between carotenoid intake, mental health, and sleep quality among university students.
Article in Sleep & breathing = Schlaf & Atmung, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
backgroundThe impact of carotenoid intake on the risk of mental disorders and poor sleep quality is unclear. Thus, we sought to examine the association between carotenoid intake, mental health, and sleep quality among university students.
methodsA total of 368 healthy university students (181 men, 49%), aged 18 to 43 years, volunteered for this study. Dietary intake, physical activity, sleep quality, mental health, and body mass index (BMI) were evaluated. A multivariable logistic regression analysis test was used to estimate the odds ratio (OR) and 95% confidence interval (CI).
resultsThe mean age of the participants was 22.9 ± 3.9 years and mean BMI was 23.1 ± 3.8 kg/m
conclusionIt appears that the students with higher carotenoid intake may have a better quality of sleep and lower risk of depression. More longitudinal and in-depth qualitative and quantitative research, with a longer-term follow-up, is needed to support the veracity of our findings.
