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
backgroundAdherence to a Mediterranean diet and better sleep health have independently been associated with a lower risk of metabolic syndrome (MetS); however, their combined effect has rarely been considered.
objectivesThis study aimed to examine whether sleep duration modifies the association between adherence to the alternate Mediterranean (aMed) diet and MetS among midlife Mexican women.
methodsThe analytic sample consisted of 410 women with a mean age of 48.2 ± 6.1 years participating in the Early Life Exposure in Mexico to ENvironmental Toxicants (ELEMENT) study. Diet was assessed with a validated food frequency questionnaire (FFQ). The mean daily sleep duration was measured with 7-d wrist actigraphy (Actigraph GTX-BT). MetS was defined on the basis of the American Heart Association/National Heart, Lung, and Blood Institute criteria. Multivariable logistic regression models were used to estimate the association between higher adherence to the aMed diet and MetS and between sleep duration and MetS, each controlling for age, socioeconomic status, and moderate-to-vigorous physical activity. To assess the potential modifying role of sleep duration, stratified analysis by sleep status was conducted, where participants were categorized as having adequate sleep (≥7 h/d) or inadequate sleep (<7 h/d) on average across the week. Statistical interaction was also tested in a logistic model.
resultsMetS was identified in 49.8% of participants, and 56.6% had a mean sleep duration of <7 h/d. Neither higher adherence to the aMed diet nor sleep duration alone was associated with MetS. However, the stratified analysis showed that among women with inadequate sleep, higher adherence to the aMed diet was related to 16% lower odds of MetS (odds ratio: 0.84; 95% CI: 0.69, 0.99; P-interaction = 0.09).
conclusionsAssociations between diet and MetS are only observed in the presence of inadequate sleep duration, suggesting a potential interaction that warrants further investigation through longitudinal research.
