Framework for Identifying Signature Foods for Health in the Children's Healthy Living Program in the United States Affiliated Pacific Region.

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
backgroundSince diet adequacy depends in part on the quality of the local food supply, policy makers, farmers, and nutritionists need to know which foods to focus on to improve dietary adequacy and nutrition related health.
objectivesThe Children's Healthy Living (CHL) Food Systems resilience project, which includes 5 United States-Affiliated Pacific (USAP) jurisdictions, developed a framework to identify "Signal Nutrients" and "Signature Foods" for food-system interventions to improve the diet and health of USAP children.
methodsThe framework identifies "Signature Foods," defined as foods consumed by the population and associated with health conditions, which can be used as leverage points to affect health and the food system. The framework was applied to 2543 CHL children aged 2-8 y using food records and anthropometric measures. The intermittent consumption of foods made direct identification of foods associated with health difficult. Therefore, the framework first identified "Signal Nutrients" associated with health conditions (overweight, obesity, and acanthosis nigricans) using logistic regression. The analysis was then repeated for Signal Nutrients sourced from specific food types and food classes to identify the food items driving nutrient associations. Foods strongly associated (standardized [Std] β: >0.025 in absolute value) with health conditions, and in the same direction as the Signal Nutrients, were designated as Signature Foods.
resultsThe framework identified 6 Signal Nutrients and 26 Signature Foods. For example, the Signal Nutrient calcium was found to be inversely associated with obesity (P = 0.0002). Twenty-four foods that contributed to calcium intake were examined for their association with obesity. Signature Foods identified for obesity and calcium were milk (Std β: ∼0.08), dairy other than milk (Std β: 0.06), fresh fish (Std β: 0.03), and cereal (Std β: 0.11).
conclusionsIdentifying strategic uses of limited resources for nutrition and health promotion can be aided by a framework that utilizes objective data sources and knowledge of community partners. Fish may be considered a potential intervention point to promote, given its importance to the USAP region and because campaigns to increase child milk consumption already exist.
