Evaluation of the Feasibility and Construct Validity of a Novel Method to Measure Household Fruit and Vegetable Procurement in Low-Income Community Settings.
Article in Journal of the Academy of Nutrition and Dietetics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundMany interventions focus on improving fruit and vegetable (F/V) procurement for those experiencing low incomes or food insecurity. To address current F/V procurement measurement limitations, a novel F/V procurement tool was developed.
objectiveThe main objectives are to describe the tool and evaluate the tool's feasibility and construct validity.
designThis cross-sectional study used baseline data from the ongoing Mobile Food Market Cluster Randomized Trial, conducted in the Twin Cities metropolitan area of Minnesota. PARTICIPANTS/
settingDuring 2023, participants (mean age = 64 years) residing in subsidized housing completed surveys and three 24-hour dietary recalls, and they recorded 4 weeks of F/V procurement using a novel tool submitted weekly by mail. The tool captured F/V items and amounts procured for the home from any type of procurement location, including food pantries. For inclusion in analysis, Wave 1 and 2 trial participants (N = 161) must have completed at least 3 of 4 F/V procurement booklets; 87% (n = 140) met this threshold.
main outcome measuresMain outcomes were Healthy Eating Index-2020 score, Healthy Eating Index-2020 Total Fruit and Total Vegetable component scores, and daily F/V servings consumed. STATISTICAL ANALYSES PERFORMED: Descriptive statistics assessed feasibility data (eg, booklet completion rates) and F/V servings by location/source data. The F/V procurement tool's construct validity was assessed with adjusted linear models testing associations between average weekly servings procured of F/V combined, fruit only, and vegetables only, and dietary and survey measures.
resultsOn average, 58% of weekly F/V servings procured were from a supermarket and 19% from a food pantry. In adjusted models, each 10-serving increase in F/V procurement was significantly associated with a higher Healthy Eating Index-2020 score by 1.8 points (95% CI, 0.6 to 2.9), Healthy Eating Index-2020 Total Fruit component score by 0.2 points (95% CI, 0.1 to 0.4), and daily F/V intake by 0.2 servings (95% CI, 0.1 to 0.3). No other measures were significantly associated with F/V servings procured.
conclusionsThis novel F/V procurement tool may be a feasible method for comprehensively measuring various ways F/V enter households. Construct validity was observed for most diet quality and dietary intake measures examined.
