Development and Validation of the South African Diet Quality Index for Pregnancy: The NuEMI Study.
Article in Food and nutrition bulletin, 2024. 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
backgroundDiet quality indexes (DQIs) consist of combinations of foods and/or nutrient components that represent adherence to dietary guidelines. A high-quality diet during pregnancy contributes to optimal birth outcomes.
objectiveWe developed and validated the first DQI for pregnancy for South African women.
methodsThe South African Food Based Dietary Guidelines and pregnancy dietary guidelines were used as theoretical basis for the
resultsA lower household density ratio, household access to a toilet, refrigerator, and microwave, a higher educational level, being employed and being food secure were significantly associated with a higher score. After correcting for energy intake, higher scores were significantly associated with higher intakes of protein, total fat, saturated fat, cholesterol, calcium, vitamin A, vitamin E, folic acid, vitamin B12, and vitamin C. Significantly more participants who were vitamin A deficient scored in the lowest tertile than those in higher tertiles.
conclusionThe SA-DQI-P is the first DQI developed for a South African population and has proven to be valid in ranking diet quality in pregnant women in our sample. Information regarding diet quality of this vulnerable group can assist with planning nutrition intervention programs to improve nutritional status.
