Skin Carotenoid Score Level and Race Affect Intradevice Repeatability of Veggie Meter® at a Single Time Point.
Article in Journal of nutrition education and behavior, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTo compare the reliability of 2 methods (3 scan average vs average of scan 2 and 3) of skin carotenoid score (SCS) measurement and identify participant-level factors affecting intradevice repeatability of Veggie Meter® (VM).
designCross-sectional study in Illinois.
participantsThe sample (N = 587) included about 36% children, 27% adolescents, and 32% adults; 67% were White, 14% Asian, 10% Black or African American, 8% mixed race, 1% Native Hawaiian, and 0.4% American Indian; 92% were non-Hispanic, and 53% female. VARIABLE MEASURED: Three consecutive SCS readings using 2 devices. Self-reported or parent-reported demographic information. ANALYSIS: Paired sample t-tests compared the coefficient of variation of the 3-scan average SCS with the coefficient of variation of the second and third-scan average SCS. We conducted sign tests and generated Bland-Altman plots to determine the type of errors. Kruskal-Wallis and Mann-Whitney tests assessed if repeatability coefficients of the 3 consecutive SCS readings were different across age, race, ethnicity, and SCS quartiles, where repeatability coefficients = within-subject SD × √2 × 1.96.
resultsAveraging the second and third scans of SCS produced 1.2% higher reliability in VM 1 and 0.7% higher reliability in VM 2 than averaging all 3 scans (t CONCLUSION AND IMPLICATIONS: Findings support using the average of the second and third scans as a more reliable method for assessing SCS. Reporting device-specific repeatability coefficients for the VM may enhance the interpretability of SCS, particularly for individuals with low SCS and for Black or African American participants.
