Validation of a Brief Vegetable Variety Questionnaire to Assess Diet Quality.
Article in Current developments in nutrition, 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
Background: Obtaining estimates of food intake via the 24-h dietary recall is laborious and expensive. Simpler methods for estimating dietary quality are needed in clinical settings and for evaluating nutrition education interventions. Objectives: The objective of this study was to validate a simple, pictorial tool for assessing diet quality using vegetable variety as the indicator. Methods: The Results: Demographic characteristics did not differ between the variety groups. The LV group had lower total HEI score (median = 54.4; IQR = 15.6) than HV (62.1; 17.3) and MV (68.0; 18.6) groups (P < 0.0001 for both). The LV variety group had a higher DED score (median = 2.6; IQR = 0.4) than the HV (2.2; 0.6) and MV (2.3; 0.5) groups (P < 0.0001 for both). Both HV and MV groups reported cooking from scratch more often than LV group ( Conclusions: This study provides evidence of the convergent and criterion validity of a simple, pictorial assessment tool for evaluating diet quality based on vegetable variety. Overall, adults with lower vegetable variety scores had lower diet quality and higher body mass index and fat mass.
