The Infant Diet Quality Index Predicts Dietary and Adiposity Outcomes in US Children 2 to 4 years old.
Article in The Journal of nutrition, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundHealthy nutrition during the first year of life is critical for optimal growth and development. Limited techniques are available to assess diet quality in infancy, and few have been shown to be predictive of dietary and adiposity outcomes in low-income children.
objectiveThe objectives of this study were to construct an Infant Diet Quality Index (IDQI) to assess the diet quality from birth to 12 mo and to determine whether the IDQI exhibits predictive validity by estimating the longitudinal associations of IDQI scores with diet quality and weight status at 2 to 4 y.
designData were analyzed from the longitudinal Women, Infants, and Children Infant and Toddler Feeding Practices Study-2 (unweighted, n = 2858; weighted. N = 392,439) using one 24-h dietary recall and survey responses during infancy. The newly constructed IDQI consists of 16 equally-weighted components: 1) breastfeeding duration; 2) exclusive breastfeeding; age of first introduction of: 3) solids, 4) iron-rich cereals, 5) cow milk, 6) sugar-sweetened beverages, 7) salty/sweet snacks, 8) other drinks/liquids, and 9) textured foods; frequency of consuming 10) fruit or 11) vegetables; frequency of consuming different 12) fruit or 13) vegetables; 14) nonrecommended bottle-feeding practices; 15) use of commercial baby foods; and 16) number of meals and snacks. Regression analysis was used to estimate associations between the total IDQI score (range, 0-1) and Healthy Eating Index-2015 (HEI-2015) scores and body mass index z-scores (BMIz) at 2 to 4 y of age, adjusted for covariates (e.g., child age, sex and race/ethnicity; maternal education level, etc.)
resultsThe total IDQI score was positively associated with HEI-2015 at the age of 2 y (β = 16.7; 95% CI: 12.6, 20.9; P < 0.001), 3 y (β = 14.5; 95% CI: 8.1, 21.0; P < 0.001), and 4 y (β = 15.4; 95% CI: 8.4, 22.4; P < 0.001); and negatively associated with BMIz at the age of 2 y (β = -1.24; 95% CI: -2.01, -0.47; P = 0.002) and 4 y (β = -0.92; 95% CI: -1.53, -0.30; P = 0.003).
conclusionsThe IDQI has predictive validity for diet quality and weight status in low-income US children.
