Long-chain omega-3 fatty acids, selenium, and mercury in relation to sleep duration and sleep quality: findings from the CARDIA study.
Article in European journal of nutrition, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
purposeTo examine the associations of long-chain omega-3 polyunsaturated fatty acids (LCω3PUFA) intake with sleep quality and duration in a cohort of American young adults, and to explore whether the associations of interest are modified by selenium (Se) and/or mercury (Hg) status.
methodsThe study sample consisted of 3964 men and women from the longitudinal Coronary Artery Risk Development in Young Adults (CARDIA) study, aged 25.0 ± 3.6 at baseline. Intake of LCω3PUFA was assessed using an interviewer-administered dietary history questionnaire at baseline (1985-1986), Y7 (1992-1993), and Y20 (2005-2006). Toenail Se and Hg concentrations were quantified at Y2 (1987-1988). The outcomes were self-reported sleep quality and sleep duration measured by one question for each at Y15 (2000-2001) and Y20. Generalized estimating equation was used to examine the association between cumulative average intake of LCω3PUFA and sleep measures. Restricted cubic spline was performed to explore the potential non-linear associations of interest. Se and Hg were dichotomized by their median values to examine the potential effect modification of Se and/or Hg.
resultsWe did not observe any significant associations (linear or non-linear) of LCω3PUFA intake with either sleep quality or duration. Also, no significant association was observed in any subgroup classified by toenail Se and/or Hg concentrations. Similarly, sensitivity analysis indicated that the null associations between LCω3PUFA intake and sleep quality or duration persisted across subgroups classified by race, gender, obesity, or having small children.
conclusionFindings from this longitudinal analysis did not support the hypothesis that LCω3PUFA intake is associated with sleep quality or sleep duration.
